What You’ll Learn

It’s little known but it powers top brands like Oakley, SalesForce, and the Associated Press. After reading this in-depth page, you’ll gain answers to the following:

  • What is Yii?
  • How does it compare to similar software frameworks?

You’ll learn what Yii’s top features and uses are and how to install it.

And you’ll learn what to look for in a Yii host. I’ll also share a few personal recommendations for Yii hosts to get you started in your search.

Yii Hosting refers to web hosting that is configured to support hosting of Yii software, a PHP framework used to develop web applications.

Yii web hosts often offer:

  • One-click installation of Yii
  • Easy access to related web development software, like your choice of PHP versions and compatible databases.
  • Speed and performance needed for optimal development on the platform.
what is yii

What is Yii?

Yii is an oddly named, open source PHP framework designed for rapid development of Web 2.0 applications.

Yii stands for “simple and evolutionary” in Chinese, but at the same time it’s an acronym for “yes it is.”

Yii is a relatively new framework — version 1.1 was released in August 2013, while version 2.0 is still in beta, although it is available for download.

As of January 2018, the most current version is 2.0.9, which supports PHP7.

The framework is open source and released under the terms of the Berkeley Software Distribution (BSD) license, which means it is free but there are some redistribution limitations.

About Code Frameworks

Maybe you’ve completed some beginner PHP courses. You’re moving into intermediate PHP training and will soon be considering a variety of PHP frameworks, but you’re not sure what a framework is. Here’s a quick overview.

What is a Software Framework?

PHP developer Hampton Paulk has a good, concise definition of a software framework: “A software framework is a universal, reusable platform to develop software applications, products, and solutions.”

Software frameworks, including PHP frameworks, offer important advantages to developers working on mid-sized to large projects, including:

  • A way to keep code organized
  • Pre-built components that speed development up
  • Modular development that splits the code into sections, promoting more effective and efficient teamwork
  • An easy way to make code sections fixable and re-usable
  • Easy installation and configuration options
  • Built-in code highlighting and correction.

The Icon Motorsports website uses Craft CMS – an application built on the Yii framework. Craft also uses Twig, Guzzle, and JQuery.

What is an MVC Framework?

Yii, and other popular PHP frameworks like CakePHP, Laravel, Zend, and CodeIgniter, are “MVC” frameworks.

MVC or “Model-View-Controller” is a type of software architecture that separates the business logic of an application from its user interactions. This pattern of division is also referred to as “separation of concerns.”

The business logic (“model”) addresses the core problem being solved by the application.

It houses the data, rules, and logic of the app. There are often multiple views offered to users (such as data displayed in a variety of formats, such as visual charts, galleries, interactive lists).

The controller receives and processes input and translates it into commands sent to the model or the view.


This separation of code into into 3 interconnected parts makes it easier to re-use (re-purpose) sections of code and speeds development up.

Comparing PHP Frameworks

Once you’ve decided that a Framework is for you, you’ll need to decide on a specific framework.

What is Yii Used For?

As a generic Web programming framework, Yii can be used to develop various types of applications using PHP.

It features a component-based structure, making it scalable and suitable for the development of large-scale applications.

Yii relies on object-oriented programming (OOP).

Yii 1.1 and 2.0 are currently the most popular versions of the framework.

why use yii

Why Should I Use Yii?

Here are some reasons why you might use Yii instead of working with pure PHP:

  1. By using Yii’s built-in functions, you can speed up the development of your web application.
  2. Yii takes advantage of PHP’s more advanced features and allows you to use them with ease.
  3. If you need to customize Yii, yet you don’t want to start from scratch, you can still gain the benefits of using a framework while tailoring Yii to meet your needs.
  4. Yii’s support for testing makes it easy to write and run tests.
  5. Yii comes with built-in security and authentication features, so you don’t have to roll your own solution.
  6. Yii’s performance related tools help you ensure that your website runs as optimally as possible.
yii server requirements

Yii 1.x and 2.0 Server Requirements

The Yii framework was designed to work on Apache servers running on Windows or Linux operating systems.

However, it should work with other servers and platforms with support for PHP 5 or later versions.

Yii 1.x officially supports PHP 5.1.0 or above, while Yii 2.0, which is a complete rewrite of Yii 1.1, requires PHP 5.4.0 or above.

Some developers may need to use legacy Yii 1.1 code with modern Yii 2.0 code, which involves a bit more planning.

No Special Hosting Requirements

Since Yii is a PHP framework, it does not have any special hosting requirements.

Yii is ready to work with a default Apache web server configuration, but depending on your needs or your web application, you may need to use mod_rewrite instructions to change the configuration on virtual hosts.

You can also use Yii with Nginx. And you can use PHP with FPM (FastCGI Process Manager). The necessary documentation is on the Yii Framework website.

Yii is built on top of the PHP Data Objects (PDO) extension and can use a variety of database management systems including:


How to Install the Yii PHP Framework

You may want to start experimenting with Yii (and other PHP frameworks) on your own machine first.

Before you begin installing Yii, make sure you’ve already installed Homebrew, PHP, and Composer. This is easy to do. Jump down to the resources section at the bottom of this page to get step-by-step instructions.

The installation process is straightforward. Get the latest copy of the Yii release file and unpack the folders to /wwwroot/yii. You should end up with the following directory: /wwwroot/yii/framework.

The framework can be installed anywhere, as the /framework directory contains all framework code files and is the only directory needed when deploying applications. Multiple Yii applications can use the same installation of the framework.

Craft CMS is a little-known but fast-growning PHP app built on Yii. Craft is used by the Associated Press, Netflix, ProPublica, SalesForce and other top brands.

Also, since Yii does not have to be installed in a Web-accessible directory, only the entry script needs to be exposed to web users. This is good news from a security perspective, as it restricts access to PHP files and scripts that could be used as an attack vector.

What is the Yii DAO?

Yii provides extensive support for database programming and since Yii Data Access Objects (DAO) is built on top of PDO, it enables access to different database management systems.

Applications developed using the Yii DAO can easily be switched to a different database management system without having to modify the code. This makes Yii more flexible than many other frameworks in a wide range of situations.

Using Yii: OOP Skills Required

As far as the skill-set is concerned, developers with experience in object-oriented programming (OOP) should have an easier time getting to grips with Yii, as it is a pure OOP framework.


What are the Main Features of Yii?

Some of the major features and advantages of using Yii include:

Model-View-Controller (MVC) Design Pattern

Yii adopts MVC architecture, described above, which allows for the separation of concerns.

Essentially, you can separate your business logic from user interface-related considerations.

AJAX-enabled widgets

Yii comes integrated with jQuery, so you have access to AJAX-enabled widgets, such as auto-completed input fields, tree views, data grids, and so on. You can write your user interface with as little hassle as possible.

User Security

Role-Based Access Manager is a Yii module that implements and let you use role-based access control.

This is a simple centralized access control system.

Essentially, you create roles, which are a collection of permissions. Each role or permission can be assigned a rule, which is executed to check the authorization of a particular user.

This role-based access system means that you can make high-level changes using roles instead of manually managing permissions for users individually.


Yii supports the writing and running of unit tests with ease.

Other (more minor) features include:

  • Form input and validation
  • Easy skinning and theming
  • Support for web services
  • Internationalization and localization
  • Caching
  • Error handling and logging
  • Automatic code generation
  • Easy integration with third-party code

What Hosting Services are Available for Yii?

Although Yii is a relatively new framework, many hosts are offering packages designed for Yii users.

Since Yii does not have many exotic requirements and can run on a wide variety of platforms and databases, these plans usually don’t differ from hosting plans marketed for other PHP frameworks.

Many Web Hosts Offer these Yii Options:

  • Free Yii installation
  • Timely framework upgrades
  • Ability to extend Yii framework functionality with additional compatible modules via one-click apps

Hosting Upgrades for Yii

Due to Yii’s advanced caching abilities, which make it suited for the development of big Web 2.0 sites, many hosts are keen to offer additional RAM or SSD (Solid State Drive) upgrades, thus making the most of Yii’s caching prowess and boosting performance in the process.

Since Yii is a good choice for large-scale Web 2.0 projects, many hosts offer scalable and dedicated Yii hosting.

Dedicated Hosting and VPS

This includes:

  • Daily backups
  • Premium support
  • And other perks.

However, individuals and smaller businesses also have a lot of choices, whether they opt for VPS hosting or cloud hosting.

These packages usually come at a fraction of the cost of a dedicated Yii server, yet they tend to offer good value for money and plenty of scalability.

Get your computer ready to run Yii (and other PHP frameworks)

So you want to take Yii (or CakePHP or Zend, etc.) for a test-drive? Here are some easy steps to get your computer set up so you can run these frameworks.

For Macs:

  1. Install Homebrew
  2. Install Composer
  3. Confirm the composer.phar file
  4. Copy the composer file to usr/local/bin
  5. Install FXP plugin
  6. Install PHP
  7. Install the international extension for PHP
  8. Change the timezone in your php.ini file

Install Homebrew

Homebrew is a time-saving package manager for Macs. It gives you am easy way to install or update packages on your Mac.

Just copy this code and run it at the command line:

/usr/bin/ruby -e "$(curl -fsSL"

Install Composer

Composer is a dependency manager for PHP that’s going to save you a lot of time.

Go to the Composer homepage and click the “download” button. Then copy the code lines you see and run them in your CLI. Here’s the code:

php -r "copy('', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === '544e09ee996cdf60ece3804abc52599c22b1f40f4323403c44d44fdfdd586475ca9813a858088ffbc1f233e9b180f061')  else  echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

Confirm the composer.phar file

Now you want to look in your directory (type “ls” in the CLI). You should see a file called composer.phar.

Copy the composer file to usr/local/bin

In the command line, run:

sudo cd composer.phar /usr/local/bin/composer

By copying the initial composer file to the usr/local/bin, you can now run composer at the command line.

Test your installation of Composer

To test it run this in the CLI:

composer -v

You should see the version of Composer displayed, followed by some sample commands.


Pro Tip: Update Composer before starting new PHP framework projects

This is a good habit and prevents conflicts between package versions.

Simply run this in the CLI:

composer self-update

Install FXP plugin

Next, we’re going to install the FXP Composer asset plugin, which is an NPM/Bower dependency manager for Composer.

This is used by Yii. It lets you manage assets like CSS and JavaScript in your composer.json file.

Simply run this in your CLI:

composer global require fxp/composer-asset-plugin

Install PHP

First, check with the PHP framework you’re using to make sure you download a compatible version of PHP. The most recent version of PHP is 7.2.0.

Yii 2.0 is fully compatible with PHP 7.x. so in this example we’ll download PHP 7.2.0.

Simply run this in your CLI:

brew install homebrew/php/php72

To check which version of PHP you’re running simply run this in the command line:

php -v

Install the international plugin for PHP

Run this in your CLI:

brew install homebrew/php/php72-intl

Change the timezone in your php.ini file

This is required by the Symfony PHP framework. If you’re only going to test-drive Yii, and not Symfony, you can skip this step.

“Where’s my php.ini file?” Good question. Run this in your command line to find out where your php.ini file is located:

php --ini 

Then copy and paste that url into your browser. It’ll take you to the location, where you can open the php.ini file with a text editor.


Now search the php.ini file for “timezone.” (See yellow highlight below.)

  • Uncomment the line with no timezone listed.
  • Then either (a) copy and paste the url in the line above it to find your timezone, or (b) click here to find it.

In the example below, I had already copied my timezone so I could quickly paste it in.


For Windows

Download XAMMP

XAMMP includes PHP and comes with a lot of useful extensions for it.

Download and install XAMMP. Follow the prompts.

Make PHP available to your command line

Go to Control Panel > Systems and Security > System > change settings.

This takes you to the System Properties window.

  • Click the “Advanced” tab on the System Properties window.
  • At the bottom of the Advanced tab, click “Environment Variables.”
  • Look for and select the “Path” variable. (The Path variable indicates all of the applications that will be available on the command line.)
  • Edit the Path: add your PHP directory to the end of the Path variable line, by typing in C:xamppphp Then click “okay.”

Test the PHP installation

Go to the command line. Type:

php -v

If PHP is installed, the version you have will display.

Install Composer

Go to this Composer link. Download and run Composer-Setup.exe.

Test Composer installation

Go to the command line and type:

composer -v

If Composer is installed, the version you have will display.

Pro Tip: before creating any new projects in PHP frameworks, get in the habit of updating Composer via the command line by typing:

composer self-update

Install FXP plugin

The FXP Composer asset plugin allows you to have CSS, JavaScript, JQuery, and other front end assets pulled in to a project by Composer.

In the command line type:

composer global require fxp/composer-asset-plugin

Install Git

Composer uses Git so we want to make sure it’s installed.

Go to Git and click on “Windows build.” Download and install it.

Confirm installation of Git

In the command line, type:

git --version

If Git is installed, the version will display.

Install the international extension for PHP

This is necessary if you want to use Yii or CakePHP.

First, find the location of your php.ini file by typing this in the command line:

php --ini
  • Then open the php.ini file.
  • Do a search inside it for “intl”.
  • Uncomment the intl extension, by removing the semi-colon before it. (This makes the extension available.)
  • Then save the php.ini file.

Set the timezone of the php.ini file

This is necessary if you want to test-drive Symfony. If you don’t, just skip this step.

  • Do a search of the php.ini file for “timezone.”
  • Uncomment the timezone line by removing the semi-colon.
  • Find your timezone.
  • Add it.

    Yii Frequently Asked Questions

    • What is Yii?

      Yii is an object-oriented PHP web application framework. The name is an acronym for “Yes it is.” It was released in late 2008, but it has already managed to gain a following in several niches.

    • How is Yii pronounced?

      Yii is pronounced “yee.”

    • How popular is Yii? How many people use it?

      Exact figures are hard to come by, but anecdotal evidence and Google Trends data indicate Yii is about as popular as the PHP frameworks CakePHP and even Zend. Yii is particularly popular in some niches such as ecommerce. Some estimates indicate that several hundred thousand developers use Yii.

    • What do some people prefer Yii over Zend?

      Yii is easier to master than Zend. It can be used for more types of projects, and developers often claim it is better documented.

    • What does my server need to handle Yii?

      You should have no trouble using Yii in the vast majority of modern development environments. Shared hosting plans could be an issue in some cases, but usually it is possible to tweak a few settings and run Yii 2.0 on shared hosting as well. Your server has to support PHP 5.4 or later. It is possible to check the requirements beforehand, and this should be straightforward because Yii is well documented.

    • Is Yii 1.x compatible with Yii 2.x?

      No. Yii 2.0 is a complete rewrite of Yii 1.1.

    • How do I install Yii?

      The installation process is well documented and straightforward. The official Yii framework website offers a number of useful guides and it’s the best place to start. Yii does not have to be installed in a web-accessible directory. Some shared hosting plans may be limited and create a few issues, but in most cases you won’t have much trouble installing and running Yii on shared hosting.

    • Are there any security issues I should be aware of?

      Not really. Yii is frequently updated and the fact that you can install it in a directory that is not accessible from the web should offer an added level of security. This makes PHP scripts that could be exploited by an attacker more difficult to access and tamper with.

    • Will my hosting provider have Yii ready to go? Is it available on many packages?

      Due to its rapid growth, the framework has caught the eye of many hosting companies, so you should have no trouble finding Yii hosting packages. Bear in mind that there is nothing too special about Yii’s requirements, so you don’t need a tailor-made hosting plan. Many hosts will allow you to install and upgrade Yii with relative ease. In most cases, you should have no trouble installing additional Yii modules, either.

    • Will my host upgrade Yii on a regular basis?

      It all depends on the host and package you choose. Obviously, packages specifically designed for Yii developers tend to get regular updates. In case you are a professional working on big Yii projects, scalable dedicated Yii hosting plans are available as well, with professional support, daily backups, and other features designed for your needs.

    • Do I need to think about caching when working on serious Yii projects?

      Yii features very advanced caching capabilities, so if you are a professional developer, or if you intend to commission an elaborate, high-traffic Yii project, you should definitely consult a few experts. Depending on the number of visitors and the amount of bandwidth, you could benefit from more RAM, or faster SSD storage in various RAID configurations.

    • How does Yii compare to CodeIgniter?

      The hosting requirements are similar, although CodeIgniter is somewhat leaner. It’s easy to learn and the installation process is even simpler than with Yii. It lacks a few features found in Yii, such as full ORM support and unit tests for source code.

    • How does Cake PHP compare to Yii?

      Cake PHP has a lot of built-in functionality and is closely integrated. However, it’s not as good as Yii for big projects and it’s not as well documented.

    • How is Yii licensed?

      Yii is published under the 3-clause New BSD License. It can be used to develop free or proprietary web applications.

    • Is Yii 1.1 still supported? Is Yii 2.0 more future-proof?

      Yii 1.0 is no longer officially supported, but Yii 1.1 still is. How long it will remain so is unclear. Yii 2.0 is, of course, actively supported.

    • Why do some people avoid Yii?

      While Yii is often touted as accessible and easy to learn, it still contains a number of pitfalls for inexperienced or poorly organized developers. Some developers complain about the lack of extensions for certain applications.
