PHP创建文件夹（$ _POST）

我需要将图像上传到服务器并使用当前时间戳存储到PHP创建的目录。下面是代码的相关部分，但不能按预期工作，它不会创建文件夹，也不会打印到控制台。可能是什么问题？

编辑：

修改PHP基于下面的评论

upload.php的

<?php 
//get unique id 
$up_id = uniqid(); 
?> 

<?php 

//process the forms and upload the files 
if ($_POST) { 

//specify folder for file upload 

$user = "user"; 


//console.log("debug......."); 
echo "debug......."; 

if (!file_exists("/var/www/Scan")) { 
    mkdir("/var/www/Scan", 0777, true); 
} 

$folderName = date("Y-m-d") . "_" . date("h_i_sa") . "_" . $user; 
if (!file_exists("/var/www/Scan/$folderName")) { 
    mkdir("/var/www/Scan/$folderName", 0777, true); 
} 

$folder = "/var/www/Scan/$folderName"; 

//specify redirect URL 
$redirect = "upload.php?success"; 

//upload the file 
move_uploaded_file($_FILES["file"]["tmp_name"], "$folder" . $_FILES["file"]["name"]); 

//do whatever else needs to be done (insert information into database, etc...) 

//redirect user 
header('Location: '.$redirect); die; 
} 
// 

?>

“'$ folder =”/var/www/Scan/'.$folderName“; ''不是正确的连接;你的意思是'$ folder =“/ var/www/Scan/$ folderName”'？ – Ben

是的，同样的方式，但是为什么没有控制台输出 – CodeDezk

从PHP实现'console.log （）;''或者点符号... – MonkeyZeus

尝试理解一个简单的例子：

<?php 

//php content 
if ($_POST) { //here we are checking $_POST values that $_POST has some values. 

    //specify folder for file upload 
    $tempDir = __DIR__ . DIRECTORY_SEPARATOR . 'upload'; //it means make a directory uploads where this php file is kept. 
    if (!file_exists($tempDir)) { // if $tempDir is not there, so it will create that directory. 
     mkdir($tempDir); 
    } 

    if(!empty($_FILES))//now checking your uploaded file is not empty 
    { 
     $nm=$_FILES['file']['name']; //here $nm get the name of the file 
     $tmp=$_FILES['file']['tmp_name'];//$tmp get the temporary file stored path 
     $mDir = __DIR__ . DIRECTORY_SEPARATOR . 'uploads'. DIRECTORY_SEPARATOR .time().$nm; //this your destination path with time+nameof file as a name of file. 
     if(move_uploaded_file($tmp,$mDir)) //uploading file to your destination path, if uploaded then it will go in the if scope and echo. 
     { 
      echo "file uploaded with timestamp in uploads folder"; 
      //now redirect from here any where 
     } 
     else 
     { 
      echo "fail to upload a file"; 
     } 
    } 

} 
?>

确定这个工程，但所有人必须做的是修复一条线。我可以补充说，他不回答我。 –

是的，它已经为我工作 –

它会做一个上传目录，然后上传带有时间戳的文件。 –
