PHP Warning when using rename() function "No data available"-CodePudding

When trying to use the PHP rename function with two valid paths (source and target), I get a warning with the following message:

PHP Warning: rename(/u01/www/user/project/image.jpg,/mnt/files/archive/image.jpg): No data available

The weird thing is that the file is actually copied (not moved, the original file still exists) but has 0 bytes and is corrupted.

Tried to Google this error, but can't find any information. Maybe a permissions issue?

please check folder is writable or not.

is_writable('/mnt/files/archive/image.jpg').

Enable error reporting

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

Now add some safety checks before:

$old_name='/u01/www/user/project/image.jpg';
$new_name='/mnt/files/archive/image.jpg';

if (file_exists($old_name) && 
    ((!file_exists($new_name)) || is_writable($new_name))) {
    rename($old_name, $new_name);
}

use copy() function instaed of rename.

$old_name='/u01/www/user/project/image.jpg';
$new_name='/mnt/files/archive/image.jpg';


if ( copy($old_name, $new_name) ) {
    echo "Copy success!";
}else{
echo "Copy failed.";
}
