added a directory in the script also does not work

Permissions clear.php (755

?>

Answer 1

Problem with directory and file paths. Try adding paths to full absolute ones, like /var/www/site.ru/maps1/files

Answer 2

If the PHP script files hosted on your hosting have access rights 777, then the execution of these scripts may be blocked by the server and you will be shown an error 500. This happens due to the fact that the access rights 777 allow everyone to make any changes to this file, which significantly affects the security and integrity of your site.

Most likely, the php file needs just 755 rights, but 777 for the deleted files, you can check the correctness of the path like this:

if (file_exists($filename)) {
    echo "Файл $filename существует";
} else {
    echo "Файл $filename не существует";
}

Answer 3

exec('rm -rf maps1/files/*');

Answer 4

If the script is in the same directory where you need to delete the files.

<?php
if (file_exists(__DIR__.'/maps1/files')) {
    foreach (glob(__DIR__.'/maps1/files/*.png') as $file) {
        unlink($file);
    }
}
