Hello,

I am trying to log all php script errors from a virtualhost to a file.
A callback function is not the solution I am looking for.

I have tried to the following settings in my httpd.conf (apache) to no
avail.

php_admin_flag display_errors off
php_admin_flag log_errors on
php_admin_flag error_log /tmp/phplog

When an erroneous file is viewed, errors are not displayed (as expected),
however the file /tmp/phplog is not created.

I'd be grateful for any help.

Thank you.
