php复制功能从一个文件夹到另一个

Question

Here is my code, what I am trying to do is take the file post.php or $file from the root of the directory that it is originally from, then put it inside this uniqueID directory, or it should finally arrive in the $newFolder5 variable to complete. The $root in the !copy function is a path pointing to the file inside the current directory, then it should go it the $newFolder5 directory when the copy function is executed on the page load. Can $root or the source of the copy be a string with a directory to the file?

<?php
$unique = uniqid();
$root = '/gallry/' . $dir_auth1 . '/'. 'post.php';
$folder = mkdir($unique, 0755); 
$uniqueFolder = '/' . $unique . '/' . 'post.php';
$destination2 = $dir_auth1 . '/'  . $unique . '/' . 'post.php';
$newFolder = '/' . $dir_auth1 . $uniqueFolder;
 
if (!copy($root, $newFolder)) {
    echo "    status not created."; 
 
} else {
    echo "Success!";
 
 
}
?>

I changed $dir_auth1 to 'aidan', since that is the root directory that the post.php is in.

In short, what Im trying to do is create a folder/directory with a uniqid() and put post.php inside of it. Or copy it.

You're not creating the same directory that you're trying to copy into.

$unique = uniqid();
$root = "/gallry/$dir_auth1/post.php";
$uniqueFolder = "/$dir_auth1/$unique";
$destFile = "$uniqueFolder/post.php";
if (mkdir($uniqueFolder)) {
    if (copy($root, $destFile)) {
        echo "Success!";
    } else {
        echo "  status not created";
}
} else {
    echo "Unable to create folder $uniqueFolder";
}
