ExtensionGuesser

class ExtensionGuesser implements ExtensionGuesserInterface

A singleton mime type to file extension guesser.

A default guesser is provided. You can register custom guessers by calling the register() method on the singleton instance:

$guesser = ExtensionGuesser::getInstance();
$guesser->register(new MyCustomExtensionGuesser());

The last registered guesser is preferred over previously registered ones.

Methods

static ExtensionGuesser getInstance()

Returns the singleton instance.

register(ExtensionGuesserInterface $guesser)

Registers a new extension guesser.

string guess(string $mimeType)

Tries to guess the extension.

Details

Return Value

ExtensionGuesser

register(ExtensionGuesserInterface $guesser)

Parameters

ExtensionGuesserInterface $guesser

string guess(string $mimeType)
