php - 为什么move_uploaded_file不允许我将它存储到我的驱动器？

Question

the below demo of code is suppose to store my image into a directory, however, using xammp i am confused on if i need permission to store it there as i am getting warnings and the file is not saving where i would like it to go.

<?php
//simple image check using getimagesize() instead of extensions
if($_FILES)
{
    $empty_check = getimagesize($_FILES['file']['tmp_name']);
    if(empty($empty_check))
    {
        echo 'this is not an image';
    }
    else
    {
        echo 'you have uploaded ' . explode('.',$_FILES['file']['name'])[0].' and it is a ' . explode('.',$_FILES['file']['name'])[1].'.';
        //an example of how i would extract the extension
        $target = "C:\xampp\tmp";
        move_uploaded_file($_FILES['file']['tmp_name'], $target);
    }
}
?>

Escape the backslashes in your path!:

$target = "C:\xampp\tmp";
//should be
$target = "C:\\xampp\\tmp";

Considering \t is interpreted as a tab, your path reads like this:

$target = "C:[?]ampp    mp";

But really, you can just use the forward slashes:

$target = '/xampp/tmp';

If this still doesn't work, make sure you have write-rights on that directory, and fix that if necessary

Then, finally read the docs:

move_uploaded_file($_FILES['file']['tmp_name'], $target.'/filename_here.ext');

You have to add the file name to the target argument!
