class MimeTypeGuesser implements MimeTypeGuesserInterface

A singleton mime type guesser.

By default, all mime type guessers provided by the framework are installed (if available on the current OS/PHP setup).

You can register custom guessers by calling the register() method on the singleton instance. Custom guessers are always called before any default ones.

$guesser = MimeTypeGuesser::getInstance();
$guesser->register(new MyCustomMimeTypeGuesser());

If you want to change the order of the default guessers, just re-register your preferred one as a custom one. The last registered guesser is preferred over previously registered ones.

Re-registering a built-in guesser also allows you to configure it:

$guesser = MimeTypeGuesser::getInstance();
$guesser->register(new FileinfoMimeTypeGuesser('/path/to/magic/file'));

Properties

protected array $guessers All registered MimeTypeGuesserInterface instances.
