array (     [0] => array         (             [path] => css/formvalidation/formvalidation.css             [name] => formvalidation.css         )      [1] => array         (             [path] => css/bootstrap-theme.css             [name] => bootstrap-theme.css         ) )

i dont know how handle recursive array folders.

ok, here's solution recursive call of function.

code

    <?php         $data = array(             'formvalidation' => array (                    0 => 'formvalidation.css'             ),             0 => 'bootstrap-theme.css',             1 => 'bootstrap-theme.min.css',             2 => 'bootstrap.css',             3 => 'bootstrap.min.css',             4 => 'component.css',             5 => 'custom.css',             'slider' => array (                 0 => 'ajaxloader.gif',                 1 => 'owl.theme.css',             ),             19 => 'validationengine.jquery.css',         );          $initpath = 'css';         echo '<b>input</b><pre>'; var_dump($data); echo '</pre>';    // testing purpose         $result = extractstylesheets($data, $initpath);         echo '<b>result</b><pre>'; var_dump($result); echo '</pre>'; // testing purpose          function extractstylesheets($input,$path='') {             $result = array();             $success = true;             foreach($input $key => $item) {                 if (is_array($item)) { // it's array, have sub-level                     // recursive call of function , merging arrays                     $result = array_merge(                         $result,                          extractstylesheets($item,$path . (empty($path) ? '' : '/') . $key)                     );                 } else {                     // style sheets                     if (preg_match('/(.*?\.css)/i', $item, $regs)) {                         // push sub-array result array                         $result[] = array(                             'path' => $path . '/' . $item,                             'name' => $item                             );                     }                 }             }             return $result;         }     ?>

result

array(9) {     [0]=> array(2) {          ["path"]=> string(37) "css/formvalidation/formvalidation.css"         ["name"]=> string(18) "formvalidation.css"     }     [1]=> array(2) {         ["path"]=> string(23) "css/bootstrap-theme.css"         ["name"]=> string(19) "bootstrap-theme.css"     }     [2]=> array(2) {         ["path"]=> string(27) "css/bootstrap-theme.min.css"         ["name"]=> string(23) "bootstrap-theme.min.css"     }     [3]=> array(2) {         ["path"]=> string(17) "css/bootstrap.css"         ["name"]=> string(13) "bootstrap.css"     }     [4]=> array(2) {         ["path"]=> string(21) "css/bootstrap.min.css"         ["name"]=> string(17) "bootstrap.min.css"     }     [5]=> array(2) {         ["path"]=> string(17) "css/component.css"         ["name"]=> string(13) "component.css"     }     [6]=> array(2) {         ["path"]=> string(14) "css/custom.css"         ["name"]=> string(10) "custom.css"     }         [7]=> array(2) {         ["path"]=> string(24) "css/slider/owl.theme.css"         ["name"]=> string(13) "owl.theme.css"     }     [8]=> array(2) {         ["path"]=> string(31) "css/validationengine.jquery.css"         ["name"]=> string(27) "validationengine.jquery.css"     } }
