error_reporting qestion.

Hi, I use Apache and I like to set the error reporting level in the http.conf file. I have the following line php_admin_value error_reporting E_ALL which doesn't seem to work at all since even a parse error does not produce an error message. Is it the case that error level macros are not supported when set in the apache configuration file? Another question (sorry :) is that the PHP documentation indicates that E_ALL is supposed to set all error reporting levels on but a comment further indicates that only the first 4 error levels are turned on by E_ALL, could someone clarify please? Thanks in advance, Rob.
