1.2.1263. Unknown Parameter Name¶
The name of the parameter doesn’t belong to the method signature. Named arguments were introduced in PHP 8.0.
Named arguments errors will also arise when spreading a hash array with arbitrary number of arguments. For example, with array_merge(), the array should not use named keys.
<?php
// All good
foo(a:1, b:2, c:3);
foo(...['a':1, 'b':2, 'c':3]);
// A is not a parameter name, it should be a : names are case sensitive
foo(A:1, b:2, c:3);
foo(...['A':1, 'b':2, 'c':3]);
function foo($a, $b, $c) {}
array_merge(['a' => [1], 'b' => [2]]);
?>

1.2.1263.1. Suggestions¶
