Composer
|
||
|
|
========
|
||
|
|
|
||
|
|
Yii2 uses Composer as its package manager. It is a PHP utility that allows you to automatically install libraries and
|
||
|
|
extensions keeping them up to date and handling dependencies.
|
||
|
|
|
||
|
|
Installing Composer
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
Check the official guide for [linux](http://getcomposer.org/doc/00-intro.md#installation-nix) or
|
||
|
|
[Windows](http://getcomposer.org/doc/00-intro.md#installation-windows).
|
||
|
|
|
||
|
|
Adding more packages to your project
|
||
|
|
------------------------------------
|
||
|
|
|
||
|
|
After [installing an application](installing.md) you will find `composer.json` in the root directory of your project.
|
||
|
|
This file lists packages that your application uses. The part we're interested in is `require` section.
|
||
|
|
|
||
|
|
```
|
||
|
|
{
|
||
|
|
"require": {
|
||
|
|
"Michelf/php-markdown": ">=1.3",
|
||
|
|
"ezyang/htmlpurifier": ">=4.5.0"
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Here you can specify package name and version. Additionally to Yii extensions you may check
|
||
|
|
[packagist](http://packagist.org/) repository for general purpose PHP packages.
|
||
|
|
|
||
|
|
After packages are specified you can type either
|
||
|
|
|
||
|
|
```
|
||
|
|
php composer.phar install
|
||
|
|
```
|
||
|
|
|
||
|
|
or
|
||
|
|
|
||
|
|
```
|
||
|
|
php composer.phar update
|
||
|
|
```
|
||
|
|
|
||
|
|
depending if you're doing it for the first time or not. Then, after some waiting, packages will be installed and ready
|
||
|
|
to use. You don't need anything to be configured additionally.
