FTP没权限直接删除目录，写的一个小工具循环删除

$path = '/var/www/html/Runtime/';

$ite = new RecursiveDirectoryIterator($path);
foreach (new RecursiveIteratorIterator($ite) as $filename=>$cur) {
    $fn = $cur->getBasename();
    if($cur->isDir() || ($fn == '.' || $fn == '..')) continue;
    unlink($filename);
}

del_dir($path);

function del_dir($path){
    $filenames = scandir($path); 
    for($i=0;$i<count($filenames);$i++) { 
        $filename = $filenames[$i];
        $url = $path.$filename."/";
        if($filename == '.' || $filename == '..') continue;
        del_dir($url);
        rmdir($url);
    }
    rmdir($path);
}
echo "success!";
