Yii Web Programming Framework

Thank you for choosing Yii - a high-performance component-based PHP framework.

Note that Yii 1.1 has reached end of life and will only receive necessary security fixes and fixes to adjust the code for compatibility with PHP 7 and 8 if they do not cause breaking changes. This allows you to keep your servers PHP version up to date in the environments where old Yii 1.1 applications are hosted and stay within the version ranges supported by the PHP team.

Currently tested and supported up to PHP 8.5.

INSTALLATION

Please make sure the release file is unpacked under a Web-accessible directory. You shall see the following files and directories:

  demos/               demos
  framework/           framework source files
  requirements/        requirement checker
  CHANGELOG            describing changes in every Yii release
  LICENSE              license of Yii
  README               this file
  UPGRADE              upgrading instructions

REQUIREMENTS

The minimum requirement by Yii is that your Web server supports PHP 5.1.0 or above. Yii has been tested with Apache HTTP server on Windows and Linux operating systems.

Please access the following URL to check if your Web server reaches the requirements by Yii, assuming "YiiPath" is where Yii is installed:

  http://hostname/YiiPath/requirements/index.php

QUICK START

Yii comes with a command line tool called "yiic" that can create a skeleton Yii application for you to start with.

On command line, type in the following commands:

    $ cd YiiPath/framework                (Linux)
    cd YiiPath\framework                  (Windows)

    $ ./yiic webapp ../testdrive          (Linux)
    yiic webapp ..\testdrive              (Windows)

The new Yii application will be created at "YiiPath/testdrive". You can access it with the following URL:

    http://hostname/YiiPath/testdrive/index.php
