Installation

CompatInfo may be installed in several ways, choose your favorite.

Please read the migration guide v3 in case you are upgrading from a version 2.x of PHP CompatInfo.

Requirements

Before you install PHP CompatInfo, you will need an operating system with PHP 5.4.0 or later installed,

CompatInfo requires the json, libxml, pdo (sqlite driver), pcre, and spl extensions. These extensions are usually compiled and enabled by default.

Composer

Put a file named composer.json at the root of your project, with the content below:

{
    "require": {
        "bartlett/php-compatinfo": "5.0.12"
    }
}

And ask Composer to install the dependencies:

$ php composer.phar install

With composer install or create-project commands, if you want to disable installation of require-dev packages (doctrine/cache, psr/log, monolog/monolog, bartlett/phpunit-loggertestlistener), don’t forget to specify the --no-dev option.

You can also use Composer to create a new project from an existing CompatInfo package. This is the equivalent of doing a git clone checkout followed by a composer install of the vendors.

$ php composer.phar create-project bartlett/php-compatinfo /path/to/install 5.0.12

Where /path/to/install is your install directory.

PHAR

The recommended way for newbies, or just to have a look on features of this library, is to download a PHP Archive that contain all required dependencies of PHP CompatInfo bundled in a single file.

$ wget http://bartlett.laurent-laville.org/get/phpcompatinfo-5.0.12.phar
$ chmod +x phpcompatinfo-5.0.12.phar
$ mv phpcompatinfo-5.0.12.phar /usr/local/bin/phpcompatinfo
$ phpcompatinfo

You can also immediately use the PHAR after you have downloaded it.

$ wget http://bartlett.laurent-laville.org/get/phpcompatinfo-5.0.12.phar
$ php phpcompatinfo-5.0.12.phar
