1.2.298. Could Use Promoted Properties¶
Promoted properties are a syntax notation where the properties are declared as arguments of the constructor.
They reduce PHP code at __construct() time. This feature is available in PHP 8.0.
<?php
class x {
function __construct($a, $b) {
// $a argument may be promoted to property $c
$this->c = $a;
// $b argument cannot be upgraded to property, as it is updated.
// Move the addition to the new call, or keep the syntax below
$this->d = $b + 2;
}
}
?>
