Cast Operator¶

Cast operators change the type of the variable to the desired type. Conversion between the current format and the target format may happen.

The available casts are:

(int), (integer): cast to integer
(bool), (boolean): cast to boolean
(float), (double): cast to float
(string): cast to string
(array): cast to array
(object): cast to object, of type stdclass. There is no operator to convert to a specific class type.
(void): complement operator to the NoDiscard attribute. It is not really a cast operator.
(unset): cast to NULL, deprecated since PHP 7.2
(real): cast to float.

<?php

    $foo = 10;               // $foo is an integer
    $bar = (boolean) $foo;   // $bar is a boolean

?>
