if (getenv(‘PHP_DEBUG’)==’1′)
{
error_reporting( E_ERROR | E_USER_ERROR );
ini_set( ‘display_errors’, true );
}
else
{
error_reporting( E_ERROR | E_USER_ERROR );
ini_set( ‘display_errors’, false );
}
And then on the development server you could have the following line in your .htaccess or VirtualHost directive:
SetEnv PHP_DEBUG=1
