typecast

[Ninjakreborn]

is it best to typecast each and every variable you use, like to make it a habit of always and every single time you create a variable you typecast it to what you want it to be set too.

[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--](int), (integer) - cast to integer
(bool), (boolean) - cast to boolean
(float), (double), (real) - cast to float
(string) - cast to string
(array) - cast to array
(object) - cast to object[/quote]
Like:
[code]<?php
$foo = 10;   // $foo is an integer
$bar = (boolean) $foo;   // $bar is a boolean
?>[/code]

one more quick question then, that helps alot, but should I ALWAYS type cast, for any specific purpose, or just for specific reasons, if so what reasons.
