Displaying PHP Errors on Ubuntu

Default configuration of PHP 5.3 / Apache 2.2 installation on Ubuntu 10.10 Maverick Meerkat does not display any syntax errors and simply throws an Internal Server Error (HTTP Error 500).

How to enable display/output of PHP 5 error messages :

1. Edit /etc/php5/apache2/php.ini
2. Set the following configuration values:

   display_errors = on
   display_startup_errors = on
   html_errors = on

3. The default error_reporting threshold is :

   error_reporting = E_ALL & ~E_DEPRECATED

   which should be enough. But you can change it if you want.
