There are quite a few bad streams usages there.
I'd rewrite your code like this:
$words = fopen('/usr/share/dict/words', 'r');
stream_copy_to_stream($words, $pipes[0]);
fclose($pipes[0]);
fclose($words);
$output = stream_get_contents($pipes[1]);
fclose($pipes[1]);
proc_close($process);
My guess at the cause of the problem was that you're tying to write
2MB into a pipe, and the underlying write() syscall could only write
64k; since you're ignoring the return code from fwrite(), you're
missing this vital fact.
Using the streams functions in PHP 5 helps you to write code that
"does what I mean", and makes for shorter, more readable code.
