Error Identifier: property.override
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);
class Foo
{
public int $foo;
}
class Bar extends Foo
{
#[\Override]
public int $foo;
#[\Override]
public int $bar;
}
Why is it reported? #
The #[\Override] attribute on a property declares that the property is intended to override a property from a parent class. If the parent class does not have a property with the same name, the attribute is incorrect. This prevents situations where a parent property is renamed or removed but the child class still claims to override it.
In the example above, Bar::$foo correctly overrides Foo::$foo, but Bar::$bar has the #[\Override] attribute even though Foo does not have a $bar property, which is an error.
This feature requires PHP 8.5 or later for the #[\Override] attribute on properties.
How to fix it #
If the property is not meant to override a parent property, remove the #[\Override] attribute:
<?php declare(strict_types = 1);
class Bar extends Foo
{
#[\Override]
public int $foo;
- #[\Override]
public int $bar;
}
If the property should override a parent property, verify the parent class actually declares a property with the same name, or fix the property name to match:
<?php declare(strict_types = 1);
class Bar extends Foo
{
#[\Override]
public int $foo;
#[\Override]
- public int $bar;
+ public int $baz; // if Foo has $baz
}
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.
