cssmin reduces the size of stylesheet definitions by removing all unneeded whitespaces and comments.

Nothing special but has the same syntax as jsmin.

Requirements:

• PHP 5.x

Syntax:

string cssmin::minify(string $css, mixed [$options])

1. $css = stylesheet definitions as string.
2. $options = array or comma separated list of options.

Options

1. remove-last-semicolon: Removes the last semicolon in the style definition of an element (activated by default).
2. preserve-urls: Preserves every url defined in an url()-expression. This option is only required if you have defined really uncommon urls with multiple spaces or combination of colon, semi-colon, braces with leading or following spaces.

Example:

include("cssmin.php");

// without options
file_put_contents("path/to/target.css", cssmin::minify(file_get_contents("path/to/source.css")));

// with the options remove-last-semicolon and preserve-urls
file_put_contents("path/to/target.css", cssmin::minify(file_get_contents("path/to/source.css"), "remove-last-semicolon,preserve-urls"));
