Why scripting languages are dynamically and weakly typed? and why none
of the scripting languages is compiler based?
why cant a scripting language be use like java or c++ where we can
catch type errors e.g. (string being assigned to an integer),
parameter passing at compiled time.


what is the significance of multiple dollar sign ($$...$var) in php?
e.g.
$var = "profession";
$$var = "doctor";
$$$var = "khalid";
and so on...
