PHP foreach loop


I am always using this PHP code snippet, which basically loops through an array that may or may not include nested arrays. So to make things easier, I am posting here for quick reference.

foreach ($array as $key => $value) {
	if (is_array($value)) {
		foreach ($value as $k => $v) {
			// do something
	} else {
		// do something

This code loops through the $array and checks to see if the value if each key also is an array. If so, it loops through that array as well. Basic, but frequently used.
