I was writing a shell script in PHP (4.4.2) that dealt with a rather
large array. To figure out what I needed the new memory limit to be, I
did a memory_get_usage() at the end of my script, and came up with about
5.5MB. I then set the memory limit to 8MB.
When I tried to run it, the script ran out of memory on the line:
$numwords = count($words);
However, when I switched to simply incrementing $numwords every time I
added an element to $words, the memory limit of 8MB was fine.
So my question is, if PHP does copy-on-write, why does PHP make a copy
of an array when you use count() on it, which should NOT be modifying
the array?
