ID: 26571 Updated by: alan_k@php.net Reported By: Mentaloid at hotmail dot com -Status: Open +Status: Bogus Bug Type: Scripting Engine problem Operating System: Linux 2.4.22 SMP PHP Version: 4.3.3 New Comment: If you ever find out why - reopen it :) Regards Alan Previous Comments: ------------------------------------------------------------------------ [2003-12-09 23:23:00] Mentaloid at hotmail dot com Hmm - I'm so embarrassed - this has problem has been buggin me for days, I go and make a bug report and I can't reproduce it with my original code that would for the life of me not work as expected. Now it does. This is an exact copy - database included (binary innodb copy). http://tko.mentadd.com/test/index.php Sorry to bother you guys, I know your all real busy. ------------------------------------------------------------------------ [2003-12-09 22:35:05] Mentaloid at hotmail dot com I'm unable to reproduce using your code.. (the -r is unavailable on my command line, so I droped it into a .php file and ran it that way). However, I'm also unable to reproduce it via a static 'ffffffff' string, however it will not work with a string from a sql result. strlen($fetch['test1']) shows 8 bytes, so I don't believe there is a leading or trailing null. I will do some more investigating here, and update with any more results I can dig up. The function I posted is as is, but I'll see if I can setup a source that will reproduce this for you. It could be a lot more source to sift through ;) ------------------------------------------------------------------------ [2003-12-09 22:15:49] alan_k@php.net I cant reproduce this on php5 or php4.3.2-RC Does this exhibit the same problem? php -r 'function test() { print_r(func_get_args()); } test("ffffffff","ffffffff");' ------------------------------------------------------------------------ [2003-12-09 21:23:50] Mentaloid at hotmail dot com Description: ------------ When passing a string containing 8 bytes that represents hexadecimal data such as 'ffffffff' to a user function that utilizes func_get_arg() or func_get_arg(), values become unavailable (zero length string) while func_num_args() will show that the value existed. Configure Line "'./configure' '--with-mysql=/usr/local/mysql' '--with-ftp' '--enable-sockets' '--with-apxs2=/usr/local/apache2/bin/apxs'" Apache 2.0, standard config + frontpage extensions.
