Query relate to constructors Dear Friends, I am reading PHP book & it says that unrelated constructors can be invoked as follows. <?php class A { function __construct() { echo "This is A's constructor"; } } class B { function __construct() { A::__construct(); echo "This is B's constructor"; } } $obj=new B(); ?> But i am getting an error "Non-static method A::__construct() cannot be called statically". Can someone please throw some light if there is anything i am missing in above code. Thanks Sachin Raut.
