Directory traversal and directory deletion functions in PHP

It's okay, I wrote a list of functions I want to turn off.

Includes traversing files under this folder, directory subdirectories reading current files under directories and files delete directory subdirectories under current folder and files above three functions currently do not support Chinese document Chinese directory

<?php header ("Content-type:text/html;charset=utf-8"); /** * Read the files and directories under the current directory * * @param string $path path * @return array all files that meet the criteria/function tlist (   
    $path) {$path = Iconv (' utf-8 ', ' GBK ', $path); if (!is_dir ($path)) {throw new Exception ($path.)   
    Not a directory ");   
    $arr = Array (' dir ' =>array (), ' file ' =>array ());   
    $HD = Opendir ($path); while (($file = Readdir ($HD))!==false) {if ($file = = "." | | $file = = "...")   
        {continue;} if (Is_dir ($path.)   
        /". $file)) {$arr [' dir '] = iconv (' GBK ', ' utf-8 ', $file); }else if (Is_file ($path.)   
        /". $file)) {$arr [' file '] [] = Iconv (' GBK ', ' utf-8 ', $file);   
    } closedir ($HD); The echo "Directory has:". Implode ("<br/>", $arr [' dir ']). "   
    <br/> ";   
The echo "file has:". Implode ("<br/>", $arr [' file ']);  /** * traverse the files and directories in the current directory and the directory * http://www.bianceng.cn * @param string $path path * in subfolders @return  Array all eligible file/function Blist ($path) {if (!is_dir (Iconv ("Utf-8", "GBK", $path)) {throw new Excepti On (folder. $path.

    } $arr = Array ();   
    $HD = Opendir (Iconv ("Utf-8", "GBK", $path)); while (($file = Readdir ($HD))!==false) {if ($file = = "." | | $file = = "...")   
          {continue;} $newpath =iconv (' utf-8 ', ' GBK ', $path). '

    } $hand = Opendir ($path); while (($file = Readdir ($hand))!==false) {if ($file = = "." | |  $file = = "...")   
        Continue if (Is_dir ($pAth. " /". $file)) {Dirdel ($path.)   
        /". $file); }else{@unlink ($path.)   
        /". $file);   
    } closedir ($hand);   
@rmdir ($path); }?>
