What is CssMin?

CssMin is a css parser and minfier. It minifies css by removing unneeded whitespace character, comments, empty blocks and empty declarations. In addition declaration values can get rewritten to shorter notation if available. The minification if configurable.

CssMin has some benefits. It supports the rewrite of CSS Level 3 properties to their browser specific counterparts and is able to simulate CSS Variables.

Install

CssMin is available on Packagist.org and may be included in other projects via composer require phrozenbyte/cssmin. CssMin requires PHP 5.0+

Syntax

string CssMin::minify(string $source [, array $filters = array()][, array $plugins = array()]);
  • string $source - The source css as string.
  • array $filters - The filter configuration as array (optional).
  • array $plugins - The plugin configuration as array (optional).

Example

// Simple minification WITHOUT filter or plugin configuration
$result = CssMin::minify(file_get_contents("path/to/source.css"));

// Minification WITH filter or plugin configuration
$filters = array(/* ... */);
$plugins = array(/* ... */);

// Minify via CssMin adapter function
$result = CssMin::minify(file_get_contents("path/to/source.css"), $filters, $plugins);

// Minify via CssMinifier class
$minifier = new CssMinifier(file_get_contents("path/to/source.css"), $filters, $plugins);
$result = $minifier->getMinified();
