Named Parameters And Variadic

It is possible to use the three dots ... operator and named parameters when calling a method. The unpacked array must have named arguments, and so does the arguments after it.

In PHP 8.0, it was not possible.

PHP code

<?php

function foo($a, ...$b) {
    echo $a.' '.implode(', ', $b);
}

foo(...[b => 1], a: 2);

?>

Before

Fatal error: Cannot combine named arguments and argument unpacking 

After
