Note Submitter: Wulfson at wulfden dot com ---- The last two comments (redbehelit and Jaik) are a little misguided. In a 26 element array, for ($i = 0; $i < count($arr); $i++) { works just fine, as count($arr) will return 26, which means that the loop will end as soon as $i gets iterated to 26 (26 < 26 is false). You'd only have to use count($arr) - 1 if your conditional was $i <= Jaik is correct that it's better not to use count() inside the loop construct. As mentioned in a previous comment, it'd be faster to use $size = count($arr); for ($i = 0; $i < $size; $i++) { I don't agree that foreach should be used instead of this, however. In my trials, I found that using a normal for loop was consistently faster than using a foreach (granted, not a whole lot faster, but everything counts if you're trying to optimize). foreach really ought to only be used when the array you're traversing contains associative indices.
