从ajax表单保存上传的文件

问题描述：

Its been a long time since i used php and i need some help regarding this basic function.

{
        $msg .= " File Name: " . $_FILES['fileToUpload']['name'] . ", ";
        $msg .= " File Size: " . @filesize($_FILES['fileToUpload']['tmp_name']);

        @unlink($_FILES['fileToUpload']);       
}

Suppose i have a file in the $_FILES['fileToUpload'], how do i create an upload dir if it does not exist, and save the file there?

Thanks!

答

use is_dir() to check if the directory exitst http://us.php.net/manual/en/function.is-dir.php

then use mkdir() if it doesn't exist http://us.php.net/manual/en/function.mkdir.php
