function advagg_drupal_load_stylesheet in Advanced CSS/JS Aggregation 6

Loads the stylesheet and resolves all @import commands.

Loads a stylesheet and replaces @import commands with the contents of the imported file. Use this instead of file_get_contents when processing stylesheets.

The returned contents are compressed removing white space and comments only when CSS aggregation is enabled. This optimization will not apply for color.module enabled themes with CSS aggregation turned off.

Parameters

$file: Name of the stylesheet to be processed.

$optimize: Defines if CSS contents should be compressed or not.

$reset_basepath: Used internally to facilitate recursive resolution of @import commands.

Return value

Contents of the stylesheet, including any resolved @import commands.
