Error Identifier: argument.positionalAfterNamed
Every error reported by PHPStan has an error identifier. Here’s a list of all error identifiers. In PHPStan Pro you can see the error identifier next to each error and filter errors by their identifiers.
Code example #
<?php declare(strict_types = 1);
function greet(string $first, string $last): string
{
return "$first $last";
}
greet(first: 'John', 'Doe');
Why is it reported? #
PHP does not allow positional arguments to follow named arguments in a function or method call. Once a named argument is used, all subsequent arguments must also be named. This is a compile-time error enforced by PHP itself.
In the example above, 'Doe' is a positional argument that follows the named argument first: 'John', which is not valid PHP syntax.
How to fix it #
Make all arguments after the first named argument also named:
<?php declare(strict_types = 1);
function greet(string $first, string $last): string
{
return "$first $last";
}
-greet(first: 'John', 'Doe');
+greet(first: 'John', last: 'Doe');
Alternatively, use only positional arguments:
<?php declare(strict_types = 1);
function greet(string $first, string $last): string
{
return "$first $last";
}
-greet(first: 'John', 'Doe');
+greet('John', 'Doe');
Non-ignorable error #
This error cannot be ignored using @phpstan-ignore or the ignoreErrors configuration. Non-ignorable errors indicate code that would cause a crash or a fatal error at runtime, or a fundamental problem in the analysed code that must be addressed.
