Can we use any other data type like boolean or float in case of int?

Question

Suggest me a Code for such!

Answer 1

php, by default. has a weak type-checking Mode.
what means a var can be of any Type without declaration.

$someValue = "Hello World"; //will be string
$someValue = 10; //will be int
and so on, and so on

now with php7 at the First time, strict variable declarations is introduced.
