Re: php 4.0.1 and error_reporting

Something changed with the way variables initialize. I didn't look at the what's new section, so perhaps it is by design. I don't think I updated my PHP.INI file either, so perhaps that has something to do with it as well. Anyway, Example: My code with PHP 4.0.0 looked something like this: -- $accesslevel = $HTTP_SESSION_VARS["accesslevel"]; // more code $read_access = get_read_access_from_db(); // psuedo-code // $read_access typically is 0 meaning anyone can read if ($accesslevel < $read_access) { die("You do not have the access to read this forum."); // actually it is a bit more friendly ;) } -- the session var "accesslevel" is not always initialized. In PHP 4.0.0 this uninitialized variable was NOT less than 0. After upgrading to PHP 4.0.1, this uninitialized session variable returns true if compared to less than zero. Changing the line to the following was a simple fix: $accesslevel = 0 + $HTTP_SESSION_VARS["accesslevel"]; I typically initialize variables, so I didn't run across any other problems with it. It was the only problem I ran into upgrading. I am using the Win32 ISAPI DLL, and the sessions now work great! Anyway, maybe this is part of your problem? -- Matthew Leverton - matthew@aeroinc.net - http://www.allegro.cc -----Original Message----- From: Kari Asikainen <Kari.Asikainen@imnetti.fi> To: php-general@lists.php.net <php-general@lists.php.net> Date: Thursday, June 29, 2000 4:45 AM Subject: [PHP] php 4.0.1 and error_reporting >Has error reporting changed somehow between PHP 4.0.0 and 4.0.1 because I'm >getting random notices about uninitialized variables and constants in my >scripts after I upgraded to 4.0.1.
