This is a tool that allows you to compress and concatenate stylesheets with PHP. To use it, download and import the 'CSS_Compress.php' file into your project.

Next, require it:

require 'CSS_Compress.php';

...and create a new instance of the class. When instantiating the class, as the first argument, pass either:

1. A path to the single CSS file that should be compressed
2. An array of each stylesheet that should be compressed and concatenated.

$C = new CSS_Compress( 'css/style.css' );

// or
$C = new CSS_Compress( array('css/style.css', 'css/style2.css') );

You can also pass an optional second parameter which designates where the new compressed stylesheet will be saved. If omitted, it'll use the first file name you pass, and append "_min" to the end of the string.

$C = new CSS_Compress('style.css', 'css/min/style_min.css');

If you wish to overwrite the file completely, simply set the second argument to the same path as the first.

$C = new CSS_Compress('style.css', 'style.css');

Finally, call the save method, and you're done.

$C->save();

require 'CSS_Compress.php';
$C = new CSS_Compress( 'style.css');
$C->save();

...compressed stylesheet is saved to style_min.css

require 'CSS_Compress.php';
$C = new CSS_Compress( 'style.css', 'styles.css' );
$C->save();

require 'CSS_Compress.php';
$C = new CSS_Compress( array('css/style.css', 'css/style2.css', 'css/style3.css'), 'css/min/styles_min.css' );
$C->save();

If you don't want to use these files locally, you can also pass your stylesheets to compresscss.com, which will do the work for you, and return the concatenated + compressed CSS. With this method, you don't need to download any files. Just open a blank PHP file, and paste in...

file_put_contents(
  'all_min.css',
  file_get_contents('http://compresscss.com/api.php?css=' . urlencode(file_get_contents('examples/css/style.css')))
);

Note that, if you're saving to a directory that does not exist, and you're using the API method, you'll need to create the directory first.

$css = array('examples/css/style.css', 'examples/css/style2.css');
array_walk($css, function( &$val ) {
   $val = file_get_contents( $val );
});

file_put_contents(
   'all_min.css', 
   file_get_contents("http://compresscss.com/api.php?css=" . urlencode(implode($css)))
);

file_put_contents(
   'style_min.css', 
   file_get_contents("http://compresscss.com/api.php?file_names=http://net.tutsplus.com/wp-content/themes/tuts/css/large.css,http://envato.s3.amazonaws.com/widget/widget.css")
);
