When configuring your error log file in php.ini, you can use an absolute path or a relative path. A relative path will be resolved based on the location of the generating script, and you'll get a log file in each directory you have scripts in. If you want all your error messages to go to the same file, use an absolute path to the file.

The best way is to look in your httpd.conf file and see what the default is. It could also be overridden by your specific virtual host. I start by looking at <code>/etc/httpd/conf/httpd.conf</code> or <code>/etc/apache2/httpd.conf</code> and search for error_log. It could be listed as either /var/log/httpd/error_log or <code>/var/log/apache2/error_log</code>, but it might also be listed as simply <code>logs/error_log</code>.
In this case it is a relative path, which means it will be under <code>/etc/httpd/logs/error_log</code>. If you still can't find it, check the bottom of your httpd.conf file and see where your virtual hosts are included. It might be in /etc/httpd/conf.d/ &lt;- as &quot;other&quot; or &quot;extra&quot;. Your virtual host could override it then with ErrorLog &quot;/path/to/error_log&quot;.

# If you do not specify an ErrorLog directive within a &lt;VirtualHost&gt;
ErrorLog &quot;/private/var/log/apache2/error_log&quot;

Find the line that starts with <code>ErrorLog</code> and there's your answer.
Note: For virtual hosts, you can edit the virtual hosts file <code>httpd-vhosts.conf</code> to specify a different log file location.
