php - Retreiving files based on a particular pattern -

i using function retreive files directory , sub-directories. how can display files _lang.php within directory , sub-directories?

function getdircontents($dir, &$results = array()){     $files = scandir($dir);      foreach($files $key => $value){         $path = realpath($dir.directory_separator.$value);         if(!is_dir($path)) {             $results[] = $path;         } else if($value != "." && $value != "..") {             getdircontents($path, $results);             $results[] = $path;         }     }      return $results; } $dir = './test/'; var_dump(getdircontents($dir)); 

answered question earlier, try using iterator classes

<?php function getdircontents($directory, $pattern) {     $result = array();     $objrecursivedirectoryiterator = new recursivedirectoryiterator($directory, recursivedirectoryiterator::skip_dots);     $objrecursiveiteratoriterator = new recursiveiteratoriterator($objrecursivedirectoryiterator);     // use regexiterator() grab files match $pattern     $objregexiterator = new regexiterator($objrecursiveiteratoriterator, $pattern, recursiveregexiterator::get_match);      // iterate through results     foreach ($objregexiterator $arrmatches) {        $result[] = $arrmatches[0];     }     return $result; }  $dir = './test/'; $arrdircontents = getdircontents($dir, "~^.+_lang\.php$~i"); var_dump($arrdircontents);
