move_uploaded_file false?

Question

linux

Hi all. I am working on linux ubuntu. move_uploaded_file doesn't work for me. How can I fix this.

$file_name = $_FILES['img']['name'];
    $file_tmp = $_FILES['img']['tmp_name'];
    $img_hash = time()."_".rand(1000, 9999)."_".$file_name;
    // move_uploaded_file($_FILES['img']['tmp_name'], $file_name);
    if (move_uploaded_file($file_tmp," ../user/user_img/".$img_hash)) {
        echo "File is valid, and was successfully uploaded.\n";
    } else {
        echo "Upload failed";
    }

ini_set('error_reporting',E_ALL);
ini_set('display_errors', 1);

1) paths must always be absolute for file operations. You have some kind of incomprehensible folder, lying incomprehensibly where, one level above it is not clear what.
2) A space in the path, before the "..", is it really so difficult to follow what you write.
0) Read the errors carefully , in your case, most likely there is no such folder, or rather, it is not where you came up with it for yourself.
