$my_arr[]    = $str;$tmp    = preg_replace("/[A-Z_]+/e", "\$hello['\\0']", $str);$my_arr[]    = $tmp;$tmp    = preg_replace("/[\"']?\s*\.?\s*([A-Z_]+)\s*\.?\s*[\"']/e", "\$hello['\\1']", $tmp);$my_arr[]    = $tmp;//testprint_r($my_arr);/**Array(    [0] => DIR_FS_AAA . DIR_WS_CLASSES    [1] => DIR_WS_TEMPLATE.'includes/' . DIR_WS_ADMIN.'helloworld'    [2] => template/includes/admin/helloworld')/**/
