PHP lessc::allParsedFiles方法代码示例

 /**
  * Execute lessphp on a .less file or a lessphp cache structure
  * 
  * The lessphp cache structure contains information about a specific
  * less file having been parsed. It can be used as a hint for future
  * calls to determine whether or not a rebuild is required.
  * 
  * The cache structure contains two important keys that may be used
  * externally:
  * 
  * compiled: The final compiled CSS
  * updated: The time (in seconds) the CSS was last compiled
  * 
  * The cache structure is a plain-ol' PHP associative array and can
  * be serialized and unserialized without a hitch.
  * 
  * @param mixed $in Input
  * @param bool $force Force rebuild?
  * @return array lessphp cache structure
