ID: 12154 Updated by: jmoore Reported By: ken.gregg@rwre.com Old Status: Open Status: Closed Bug Type: Reproducible crash Operating System: Win 95 SR2.1 PHP Version: 4.0.6 New Comment: Cant reproduce.. looks like its been fixed to me, please reopen if it still occurs with latest cvs version. Cheers, - James Previous Comments: ------------------------------------------------------------------------ [2001-07-13 18:26:03] ken.gregg@rwre.com array = fgetcsv(fh, length[, delim]); Documentation says length must be longer than the longest line including eol chars. But it shouldn't gp fault. Nice function. But it would sure be nice to not have to know the length of the longest line. This was a 75 mb file and it was 50% in that one line was 8K. Easily reproduced. As soon as a line longer than the length parameter is encountered, immediate gp fault. PHP caused an invalid page fault in module KERNEL32.DLL at 016f:bff78769.
