Tip #1:

Don't use count() in loops unless there are very few items to count and
performance doesn't matter, or the number will vary over the loop. That
is, don't do this:

for ($i = 0; $i < count($items); $i++)

Instead, do this:

$number = count($items);
for ($i = 0; $i < $number; $i++)

Gah!

for ($i=0;$i<sizeof($array);$i++)

is something I do all the time.
So the array size is being calculated each iteration?
