PHP实现批量重命名某个文件夹下所有文件的方法

<?php
$paths = "C://Documents and Settings//sk//Desk//s//";
$d = dir($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";
?>
