Development website; error reporting

How do i setup the perfect development website? I've added the following to "apache directives":

Code:

php_admin_flag display_startup_errors on
php_admin_flag display_errors on
php_admin_flag html_errors on
php_admin_flag error_reporting = E_ALL | E_STRICT

But the error reporting level isn't set right? I can only change the error reporting, by editing the php.ini file.

Thanks

 

I use "fast-CGI"

 

php_admin_flag works only with mod_php.

 

Okay, is there a way to change the flags, per website?

 

Take a look at chapters 5 and 6 on http://www.howtoforge.com/how-to-set-up-apache2-with-mod_fcgid-and-php5-on-debian-lenny-p2
