如何在使用 move_uploaded_file() 时在 PHP 中创建目标（文件夹）？

How to create destination (Folder) in PHP while using move_uploaded_file()?

提问by alex

I want to upload files with PHP and i use move_uplload_files to copy them to the destination folder I want, everything works fine with this :

我想用 PHP 上传文件，我使用 move_uplload_files 将它们复制到我想要的目标文件夹，一切正常：

if (move_uploaded_file($_FILES['uploadfile']['tmp_name'], './uploades/'))
die("success");
else
die("error");

But when I try this

但是当我尝试这个时

$rand =  chr(rand(97, 122)). chr(rand(97, 122)). chr(rand(97, 122));
if (move_uploaded_file($_FILES['uploadfile']['tmp_name'], './uploades/'.$rand))
die("success");
else
die("error");

I will get error, and it looks like move_uploaded_files can notcreate folders. How can I do this ?

我会收到错误消息，看起来 move_uploaded_files无法创建文件夹。我怎样才能做到这一点 ？

Basically I am looking for a way to do it like file_put_contents()that creates the path if not exist.

基本上我正在寻找一种方法来做到这一点file_put_contents()，如果不存在就创建路径。

Use mkdir().

使用mkdir().

If you need to make multiple folders, such as by passing a/b/c, set the third argument to TRUE.

如果您需要创建多个文件夹，例如通过传递a/b/c，请将第三个参数设置为TRUE。

You can test if it is already there, and add if not like so....

您可以测试它是否已经存在，如果不存在则添加....

$path = 'abc';

if ( ! is_dir($path)) {
    mkdir($path);
}

Use something like this:

使用这样的东西：

$folder = "uploads"; 
if(!is_dir($folder)) mkdir($folder);

is_dir()checks if the folder is there.

is_dir()检查文件夹是否存在。

Create the directory first using mkdir()

首先使用创建目录 mkdir()

  $rand =  chr(rand(97, 122)). chr(rand(97, 122)). chr(rand(97, 122));
    mkdir('./uploades/'.$rand);
    if (move_uploaded_file($_FILES['uploadfile']['tmp_name'], './uploades/'.$rand))
    die("success");
    else
    die("error");

This works for me:

这对我有用：

$path = "upload/";
$name = $_FILES["file"]["name"];
// Remove dangerous characters from filename.
$name = str_replace('..', '', $name);
$name = str_replace('/', '', $name);
$name = str_replace('\', '', $name);

if (($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/jpg")
&& ($_FILES["file"]["size"] < 2000000)) {
      if ($_FILES["file"]["error"] > 0) {
        echo "Error " . $_FILES["file"]["error"] . "<br>";
      } else {
        if(file_exists($path.$name)){
            echo "$path$name already exists. ";
        } else {                
            @mkdir($path, 0666, true);  // Create non-executable upload folder(s) if needed.
            move_uploaded_file($_FILES["file"]["tmp_name"], $path.$name);
            echo "Stored in: $path$name";
        }
    }
} else {
    echo "Invalid file. Allowed are JPG smaller than 2 MB.";
}

if($_FILES['file_up']['type']=='image/jpeg' || $_FILES['file_up']['type']=='image/png' || $_FILES['file_up']['type']=='image/gif')
{
    move_uploaded_file($_FILES['file_up']['tmp_name'],'uploads/'.time().$_FILES['file_up']['name']);
}
else
{
    echo "Upload only image file..";
}
