Error Identifier: enum.nameCase

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);

enum Suit
{
	case Hearts;
	case Diamonds;
}

function doFoo(suit $s): void
{
}

Why is it reported? #

The enum name is referenced with incorrect letter casing. While PHP class and enum names are case-insensitive at runtime, using inconsistent casing leads to confusion and makes code harder to maintain. The reference suit does not match the declared name Suit.

How to fix it #

Use the correct casing that matches the enum declaration:

-function doFoo(suit $s): void
+function doFoo(Suit $s): void
 {
 }

How to ignore this error #

You can use the identifier enum.nameCase to ignore this error using a comment:

// @phpstan-ignore enum.nameCase
codeThatProducesTheError();

You can also use only the identifier key to ignore all errors of the same type in your configuration file in the ignoreErrors parameter:

parameters:
	ignoreErrors:
		-
			identifier: enum.nameCase
