A lot of programmers use foreach in order to iterate an array (or something else) in order to find something. When the element is found, we can use break; in order to get out of the foreach loop and continue the execution. There are quite a lot of cases, where you want to do something if you did not find anything in foreach...

Currently, you could check whether a single variable has changed or not, but sometimes this is not really the case and the only 100% working solution is creating an extra variable that is being used as a flag ($foreachEnded = true/false), in order to know how we got out of the foreach. But this is something that should be a lot nicer when the language actually has a built-in behaviour for this.

If no else-branch exists for the foreach, it should exhibit the same behaviour as it currently does, which makes it compatible with existing php code.

Test script:
// How it should work...
$list = [1, 2, 3, 4, 5];

foreach ($list as $e) {
	if ($e == 3) {
		echo("3 has been found!");
} else {
	echo("3 has not been found!");

// Prints... 3 has been found!

// Retrying with $list = [1, 2, 4, 5];
// Prints... 3 has not been found!
