In PHP there is no need to declare the variable with
explicit type declaration. Variable type is specify by the
context.
For example, if we assign the integer value into variable,it
will be integer variable and if we assign the string value
into variable it will be string.
Example:
--------
<?php
$a=10;
$b="string";
echo "$a"; // 10
echo "$b"; // String
?>
If we want to force the variable type into different type we
can do the type casting.
Type casting example:
---------------------
<?php
$one = 10; // $one is an integer
$two = (boolean) $one; // $two is a boolean
?>
In PHP we are having function called settype() for setting
the particular variable type.
settype() example:
------------------
<?php
$first = "10rose"; // string
$second = true; // boolean
settype($first, "integer"); // $first is now 10 (integer)
settype($second, "string"); // $second is now "1" (string)
?>
