PHP Bug Type: Output Control
Bug description: logging warnings causes header() to fail
What i am trying to do: send headers
What happens: headers don't get sent under the excuse that "output already
started" if any messages have been logged by error_reporting, although no
output has been sent to the browser. (logging goes to error_log) If i
disable reporting E_NOTICE or logging, problem disappears.
this happens under php 4.3.0 and the fresh snapshot from Feb 5, when used
in cgi mode in the following ways:
Action php-script /php4/php
-or-
#!/usr/bin/php
it DOES NOT happen under mod_php 4.3.0
code that exhibits the problem:
(i expect to get redirected to ok.php but i see hi instead)
if i remove the errorneous line that causes warnings, it works as
intended.
<?php
$res=$na['na'];
header('Location: ok.php');
echo 'hi';
?>
error_log:
PHP Notice: Undefined variable: na in /www/mysite/htdocs/problem.php on
line 2
PHP Warning: Cannot modify header information - headers already sent in
/www/mysite/htdocs/problem.php on line 3
