Installation

Phar

The recommended way to install phpca is as phar-package.

1. Just download a phar from releases page
2. Make it executable and put it in one of folders listed in your $PATH:

   chmod +x phpca.phar
   sudo mv phpca.phar /usr/local/bin/phpca

Further I will use commands for PhpCodeAnalyzer installed as phar or globally with composer, but if you've installed it locally with composer, just replace phpca command with vendor/bin/phpca.

Composer

Another way to install phpca is via composer.

1. If you do not have composer installed, download the composer.phar executable or use the installer.

$ curl -sS https://getcomposer.org/installer | php

2. Run php composer.phar require wapmorgan/php-code-analyzer * or add requirement in composer.json.

{
  "require": {
    "wapmorgan/php-code-analyzer": "*"
  }
}

3. Run php composer.phar update

Global installation

You can get more profit when phpca installed globally.

1. If you do not have composer installed, look previous section and install composer on your server.

2. Run php composer.phar global require wapmorgan/php-code-analyzer

If phpca installed globally, you can use phpca command inside any directory.
