Edit report at http://bugs.php.net/bug.php?id=29100&edit=1 ID: 29100 Comment by: nasretdinov at gmail dot com Reported by: pickleman78 at sbcglobal dot net Summary: fread ignores memory_limit Status: Bogus Type: Bug Package: Reproducible crash Operating System: WIndows XP PHP Version: 4.3.6 New Comment: The this is that this does not lead to normal Fatal error, but to a web server/PHP uncatchable and undebuggable crash. Previous Comments: ------------------------------------------------------------------------ [2004-07-12 19:20:10] pollita@php.net emalloc() deosn't *actually* try to allocate the memory.

Now I would reasonably assume that since this is far above the memory limit set in my PHP.ini file memory_limit = 8M I would expect it to stop before even attempting to allocate such a rediculous ammount of memory for the script. In this case it fails with a FATAL: emalloc() unable to allocate 1761607681 bytes. Should this be what it does? I would expect it to issue an ERROR as opposed to crashing. Reproduce code: --------------- <?php $fp=fsockopen("http://php.net"); $data=fread($fp,1761607681); ?> Expected result: ---------------- It would be expected to receive an error as opposed to PHP trying to allocate this memory Actual result: -------------- Stated above, causes FATAL: emalloc() could not...... ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=29100&edit=1
