[binarycloud-dev] helper method extract_params

[Andreas A. <a.a...@th...>]

I've done a helper method that some of you might find usefull, too. It's in
global scope (non class method):

// method extract_params {{{
/**
 * Non class method extract_params extracts the params passed to
 * a module to class vars.
 * Called within the constructor method of you module like:
 *
 *     extract_params($this, $_params)
 *
 * It actually does the following:
 *
 *     - copies $_params to $this->params
 *     - references each key of $this->params to $this->key
 *
 * @param   object  The object instance this functions should applied to
 * @param   array   The parameter array passed to the constructor
 * @return  bool    True/false
 * @author  Andreas Aderhold, an...@bi...
 * @access  public
 */

function extract_params(&$_cls, $_params) {
	if (!is_array($_params)) {
		return;
	}
	$_cls->params = $_params;
	foreach (array_keys($_cls->params) as $name) {
		$_cls->$name =& $_cls->params[$name];
	}
}

// }}}
