PHP的rename()、unlink()、rmdir()函数只能操作一个目标，如何批量操作呢？比如批量重命名、删除？

用dir函数得到目录，循环
<?php
$paths = "/upload";
$d = dir($paths);
while (false !== ($entry = $d->read())) {
$table_change = array(' '=>'_');
$newName = strtr($entry,$table_change);
$newName = substr($newName, 0,-4);
rename($paths.$entry, $paths.$newName."_s.jpg");
}
$d->close();
echo "done";
?>
