register(ExtensionGuesserInterface $guesser) Registers a new extension guesser. When guessing, this guesser is preferred over previously registered ones. Parameters ExtensionGuesserInterface $guesser

string guess(string $mimeType) Tries to guess the extension. 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. Parameters string $mimeType The mime type Return Value string The guessed extension or NULL, if none could be guessed

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. re

static ExtensionGuesser getInstance() Returns the singleton instance. Return Value ExtensionGuesser
