I'd have to come up with some OTHER scenario not involving fatal error, such as: strict $db = new DB();

The example is wrong. The new operator will always return an instance of the given class (or there will be an exception). [...]

This is not true. The new operator can return NULL. In fact, the intl extension uses this extensively: $ php -d extension=intl.so -r 'var_dump(new Collator());' Warning: Collator::__construct() expects exactly 1 parameter, 0 given in Command line code on line 1 NULL (in fact, I think it's also leaking the object in this case as it should call zval_dtor before using RETURN_NULL, something I'll look closer to when I have the time) Contrast with: <?php class A { function __construct($a) {} } var_dump(new A()); Warning: Missing argument 1 for A::__construct(), called in - on line 5 and defined in - on line 3 object(A)#1 (0) { } -- Gustavo Lopes
