Question

您好我有一个网站可以上传三种类型的文件，但是当我上传时，无论上传哪种类型，它们都会变成.aiff文件。 Suuuper跛脚。我在哪里出错这个代码？：/ 非常感谢。（其中一些代码是由另一个人制作并修改的）

// Types of files that are acceptiable for uploading. Keep the array structure.
$allow_types=array("wav","mp3","aiff");

// Function to get the extension a file.
function get_ext($key) { 
    $key=strtolower(substr(strrchr($key, "."), 1));
    $key=str_replace("wav","mp3","aiff",$key);
    return $key;
}

    //Tally the size of all the files uploaded, check if it's over the ammount. 
    If(array_sum($_FILES['file']['size']) > $max_combined_size*1024) {

        $error.="<b>FAILED:</b> All Files <b>REASON:</b> Combined file size is to large.<br />";

    // Loop though, verify and upload files.
    } Else {
print $key; 
        // Loop through all the files.
        For($i=0; $i <= $file_uploads-1; $i++) {

            // If a file actually exists in this key
            If($_FILES['file']['name'][$i]) {

                //Get the file extension
                $file_ext[$i]=get_ext($_FILES['file']['name'][$i]);

三种文件类型保存为一个？
