Error Identifier: declareStrictTypes.value
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 = 'foo');
Why is it reported? #
The declare(strict_types=...) statement only accepts 0 or 1 as its value. Any other value, including strings, floats, or other integers, is invalid. PHP requires this to be either 1 (to enable strict type checking) or 0 (to disable it). This is a hard constraint enforced by the PHP language.
How to fix it #
Use 0 or 1 as the value for strict_types:
-<?php declare(strict_types = 'foo');
-+<?php declare(strict_types = 1);
+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.
