1.2.290. Could Use Class Operator¶
The class operator is ::class. With a class name as left operator, it provides the full class name.
Classes may also be identified with a string, as a fully qualified name. Using the class operator is a more explicit way to do it.
The ::class operator works with the local use expressions. It also provides a string, which may be further processed. The class operator is also called the ‘scope resolution operator’.
<?php
use A\B\C;
$a = C::class;
$a = \A\B\C::class; // also valid
$object = new $a(); // object of A\B\C.
// string version
$a = '\a\b\c';
$object = new $a(); // object of A\B\C.
?>
See also Scope Resolution Operator (::).
