1.2.119. Cast Usage¶
List of all cast usage.
PHP does not require (or support) explicit type definition in variable declaration; a variable’s type is determined by the context in which the variable is used.
Until PHP 7.2, a (unset) operator was available. It had the same role as unset() as a function.
<?php
if (is_int($_GET['x'])) {
$number = (int) $_GET['x'];
} else {
error_display('a wrong value was provided for "x"');
}
?>
