apache overriding php's error_log setting

[Daniel Convissor]

Binary package hint: apache2

# less /etc/php5/php.ini
log_errors = true
error_log = /var/log/php_errors.log

# apache2ctl restart

View phpinfo() output, showing the log_errors and error_log settings are in place.

Create a PHP script that calls a bogus function then point a web browser at it.

# less /var/log/php_errors.log

The error isn't in there.

# less /var/log/apache2/error.log

Huh. The PHP error is in there. That's not how it's supposed to work.

Running Apache 2.2.12.

Ok before we go any further we need the following:

- Which version of php are you using?
- Are you using php as a cgi or using mod_php?

Thanks

This is happening with both PHP 5.3.2RC1 and a current checkout of the PHP_5_3 branch. Both built from source from SVN by me to run as Apache modules. Only one of them is installed at a time.

Apache is apache2-mpm-prefork installed via apt-get.

Never mind. Apache didn't have permissions to create the error log. Here's how to resolve it:

mkdir /var/log/php5
chown root:www-data /var/log/php5
chmod 775 /var/log/php5

Now edit php.ini:
error_log = /var/log/php5/php_errors.log

Sorry for the noise.
