No. It is (almost) the difference between two conditionals versus one. Both are
fast, however, and you will find it hard to measure the difference unless you
have many instances of this.
If you're concerned about performance, you should also use notation such as if
(!$r) instead of if($r == 0). If you're concerned about readability, consider a
comment near your else statement that explains what condition fits there.
