Re: Fwd: [PHP] proc_open and buffer limit?

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. --Wez.
