[PHP-DEV] Bug #13933 Updated: error_log and HTTP redirect using header conflict
ID: 13933 Updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] -Status: Assigned +Status: Closed Bug Type: Output Control Operating System: Windows NT4 SP6 PHP Version: 4.0.6 Assigned To: yohgaki New Comment: This bug has been fixed in CVS. Previous Comments: [2001-12-31 19:17:16] [EMAIL PROTECTED] Assigning this to Yasuo :) [2001-12-12 04:51:21] [EMAIL PROTECTED] Zak, is this bug analyzed? I'm trying to sort out output buffering problems. Thanks. [2001-12-10 20:40:37] [EMAIL PROTECTED] Assigning it to myself so that I don't forget about it. :) [2001-12-05 04:24:00] [EMAIL PROTECTED] I finally found time to test. Here it goes. First of all, PHP config is: error_log is not set display_errors is off log_errors is on error_reporting is standard (E_ALL ~E_NOTICE) Then, the page I'm testing: ? error_log (this is a test, 0); header(Location: index.php); ? And finally, the results: - in Apache's log file, I get these two lines: [Wed Dec 05 10:09:59 2001] [error] [client 172.22.50.91] this is a test [Wed Dec 05 10:09:59 2001] [error] [client 172.22.50.91] PHP Warning: Cannot add header information - headers already sent in d:\wwwroot\htdocs\csf_recette\titi.php on line 3 - the source of the generated page displayed in IE is as follow, eventhough nothing has been output: !DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.0 Transitional//EN HTMLHEAD META http-equiv=Content-Type content=text/html; charset=iso-8859-1/HEAD BODY/BODY/HTML Conclusion: - error_log works fine, it does what I expect, but it might do a little more; - PHP complains about something being output *before* the call to header. I've tried removing this call (to header), my message is logged, and I *still* get the same output; - thus, somehow, the call to error_log produces PHP or Apache to generate this unexpected HTML code while logging; I've tried almost the same settings on another server (difference in php.ini is display_errors on) and it works quite fine. Could there be other parts of PHP's configuration, or even Apache's conf, altering the expected behaviour ?
