PHP - mkdir 文件错误

Question

当我将文件提交到我的文件目录时，我收到很多错误，例如

( ! ) 警告：mkdir(): No such file or directory in C:\wamp64\www\MT\directory.php on line 38

( ! ) 警告：move_uploaded_file(devPacks/peopl39e_8503_cheese/0kk/1501471127_adc9ebd871a68b573fd928ebff5bb54b.png)：无法打开流：C:\wamp64\www\MT\directory.php 第 40 行中没有这样的文件或目录

来自目录。我相信问题出在这行代码

$dir = "devPacks/" .$fullname."_".$userid."_".$username."/".$packname;

因为当我像这样排除“$packname”时

$dir = "devPacks/" .$fullname."_".$userid."_".$username."/".$packnames;

请注意，我在发送包名* 时添加了一个“s”，我得到了这个

( ! ) 注意：未定义变量：packnames in C:\wamp64\www\MT\directory.php 第 35 行

当我回显目录时，我得到这个“devPacks/peopl39e_8503_cheese/ “。所以我不确定发生了什么，但这是我的代码。

PHP

<?php
if($_SERVER['REQUEST_METHOD'] =="POST"){
    $currentDirectory = getcwd();
    $userid = "8503";
    $fullname = "peopl39e";
    $username = "cheese";
    $packname = "0kk";
    foreach($_FILES['file']['tmp_name'] as $key => $error){
        if ($error != UPLOAD_ERR_OK) {
            $errors[] = $_FILES['file']['name'][$key] . ' was not uploaded.';
            continue;
        }
        $file_tmp = file_get_contents($_FILES['file']['tmp_name'][$key]);
        //keep only A-Z and 0-9 and everything else KILL
        $file_name = preg_replace("/[^a-z0-9\.]/", "_", strtolower($_FILES['file']['name'][$key]));
        $file_name = strtotime("now")."_".$file_name;
        $allowed =  array('gif','png' ,'jpg');
        $ext = pathinfo($file_name, PATHINFO_EXTENSION);
        if(!in_array($ext,$allowed) ) {
            die('error');
        }
        $dir = "devPacks/" .$fullname."_".$userid."_".$username."/".$packname;
        if(is_dir($dir)==false){
            mkdir($dir, 0777);
        }
        if(!move_uploaded_file($_FILES['file']['tmp_name'][$key],$dir.'/'.$file_name)){
            die("File didn't send!");
        }
    }
    echo $dir;
}
?>
