将图像上传到远程服务器。 PHP

Question

I do the image hosting and I have a problem..

I have 3 servers.

First - Site/script

Any two servers for images.

How I Can upload image from "one" server (script) to second and third servers?

<?php
    if (isset($_POST['upload']))
    {
        $blacklist = array('.php', '.phtml', '.php3', '.php4', '.php5');
        foreach ($blacklist as $item)
        {
            if(preg_match('#' . $item . '\$#i', $_FILES['file']['name']))
            {
                echo "We do not allow uploading PHP files
";
                exit;
            }
        }

        $uploadDir  = PROJECT_ROOT . 'upload/'; // 1ST SERVER (THIS SERVER)
        $uploadFile = $uploadDir . basename($_FILES['file']['name']);

        if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadFile))
        {
            echo "File is valid, and was successfully uploaded.
";
        }
        else
        {
            echo "File uploading failed.
";
        }
    }    
?>
<form name="upload" method="post" enctype="multipart/form-data">
    Select the file to upload: <input type="file" name="file"/>
    <input type="submit" name="upload" value="upload"/>
</form>

You could use ftp. PHP has fairly easy way to do this. Check this link.
