PHP重命名、删除函数如何批量操作呢？

用dir得到，循环

<?php  
$paths = "C://Documents and Settings//sk//Desktop//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";  
?>
