php, can exceptions be thrown 2 levels up?

Question

I know this is a weird on, but in my code, i have development mode errors, and production mode errors. This is the function i have:

private function error($m

Just omit the try/catch block. Exceptions automatically propagate up as far as they can until something catches them; you don't need to explicitly re-throw them at every level of the call stack.

This...

try{
    $this -> error( "Invalid Link After Connect.", mysql_error () );
} catch ( Exception $exp ){
    throw $exp;
}

is exactly equivalent to this:

$this -> error( "Invalid Link After Connect.", mysql_error () );
