This method has been deprecated. Use forAll() instead.

Option::ifDefined( callable $callable )

This is similar to map() below except that the return value has no meaning; the passed callable is simply executed if the option is non-empty, and ignored if the option is empty.

Description

In all cases, the return value of the callable is discarded.

    $comment->getMaybeFile()->ifDefined(function($file) {         // Do something with $file here.     });

If you’re looking for something like ifEmpty, you can use getOrCall and getOrElse in these cases.

Parameters

$callable

(Required)

Return

(void)
