as a third method, you can explicitly disable warnings and errors for a
single command using the '@' modifier.
This is widely unknown but a very handy feature: having excessive
error_reporting turned on [error_reporting(E_ALL)] helps a lot in spotting
down possible problems in your code, but again there are numerous locations
where e.g. array keys might be there, or not. You could either use
array_key_exists(), or the @ modifier to suppress the warning.
Example:
// this will raise a warning
$test = $array['nonexisting_key'];
// this avoids array access if the key is not set,
// OTOH the receiving variable might be undefined
if (array_key_exists('nonexisting_key', $array))
$test = $array['nonexisting_key'];
// this is a simple, elegant, and even self-documenting solution
$test = @$array['nonexisting_key'];
