What is type casting and type juggling in php

Hey,

The way by which PHP can assign a particular data type for any variable is called typecasting. The required type of variable is mentioned in the parenthesis before the variable.

Sample code:

$str = "10"; // $str is now string $bool = (boolean) $str; // $bool is now boolean

PHP does not support data type for variable declaration. The type of the variable is changed automatically based on the assigned value and it is called type juggling.

Sample code:

$val = 5; // $val is now number $val = "500" //$val is now string

Thank You!
