  • method `mimeType()` is not declared using [static keyword](https://stackoverflow.com/questions/45476515/whats-the-difference-between-public-static-and-public-function-in-php). – Insane Skull Apr 04 '22 at 04:35

The following code:

$mimetype=DirectoryHelpers::mimeType($files_uploaded);

Change as follows:

$var = new DirectoryHelpers();
$mimetype = $var->mimeType($files_uploaded);

Or as a shorthand:

$mimetype = (new DirectoryHelpers)->mimeType($files_uploaded);

In general: It depends on your needs. If you do not need to instantiate a class, you can change your library function to static. treat static functions like constants, (can not have objects)
Example here:

class DirectoryHelpers {
    public static function mimeType() {
        // code ...
    }
}
