if ( empty($this->dir_name) ) die('You must select a directory to search'); 
foreach ( $this->myfiles as $f ){ 
if ( in_array(array_pop(explode ( '.', $f )), $this->allowed_file_types) ){ //开源OSPhP.COM.CN 
$contents = file_get_contents($f); 
if ( strpos($contents, $this->search_phrase) !== false ) 
$this->foundFiles [] = $f; 
//开源代码OSPhP.COm.CN

} 
function GetDirContents($dir){ 
if (!is_dir($dir)){die ("Function GetDirContents: Problem reading : $dir!");} 
if ($root=@opendir($dir)){ 
//PHP开源代码 

while ($file=readdir($root)){ 
if($file=="." || $file==".."){continue;} 
if(is_dir($dir."/".$file)){
