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
static ExtensionGuesser getInstance()
Returns the singleton instance.
register(ExtensionGuesserInterface $guesser)
Registers a new extension guesser.
When guessing, this guesser is preferred over previously registered ones.
string guess(string $mimeType)

The mime type is passed to each registered mime type guesser in reverse order of their registration (last registered is queried first). Once a guesser returns a value that is not NULL, this method terminates and returns the value.
