And also avoid things like if ( ++ $i < count( $profile_tabs ) ) ). Make it 2 separate lines instead

	$i ++;
	if ( $i < count( $profile_tabs ) )

The reason being, `++ $i` and `$i ++` are [two different operators and behave differently](http://php.net/manual/en/language.operators.increment.php). Use them in conditionals can be quite confusing and hard to debug.
