Renaming a file and attatching the extention

[pinehead18]

if (isset($_FILES['file']['name'])) {
    if ((($_FILES['file']['type'] == 'image/gif') || ($_FILES['file']['type'] == 'image/pjpeg')) && (($_FILES['file']['size']
< 512000))) {
                if (file_exists('pics/' . $_FILES['file']['name'])) {
            echo "File already exists!";
        } else {
// Rename file using the date rename 

// This is where I give it a new name
        $_FILES['file']['name'] = "New_name";
            move_uploaded_file($_FILES['file']['tmp_name'], $_SERVER['DOCUMENT_ROOT'] . 'pics/' .
$_FILES['file']['name']);
            echo "File uploaded sucessfully.";
        $newpicname = $_FILES['file']['name'];
        unlink($oldpic);
        }
        echo $newpicname;
        echo $name;

    }

Ok, this script will upload the file.. In fact it even renames the file to "New_name" However, the problem is that i can't attatch the original extention on to the new name.

any suggestions?

Thank you

Well, just grab the extension before renaming it. Explode on ".", the last part of the array is your extension. Then just stick it on the end when renaming.
