The function settype() will set a particular function to a specified type. The first parameter must be the variable which needs to be converted and the second parameter must be the type.

<?php
$int = 25;
$str = 'Hello world!';
$bool = true;
$arr = array(1,2,3);
$obj = new stdClass;
$str2 = 'Hello World!';

settype($int, 'string');
settype($str, 'array');
settype($bool, 'integer');
settype($arr, 'object');
settype($obj, 'array');
settype($str2, 'null');

var_dump($int);
echo '<br />';
var_dump($str);
echo '<br />';
var_dump($bool);
