Error Identifier: greaterOrEqual.invalid

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 doFoo(\stdClass $obj, int $n): void
{
	$result = $obj >= $n;
}

Why is it reported? #

The >= (greater than or equal) comparison operator is being used between two types that cannot be meaningfully compared, resulting in a PHP error. Not all types support comparison operations – for example, comparing an object to an integer is not a valid operation.

In the example above, a stdClass object is compared with an integer using >=, which PHP cannot perform.

How to fix it #

Compare values of compatible types, or extract a comparable value from the object first:

 <?php declare(strict_types = 1);
 
 function doFoo(\stdClass $obj, int $n): void
 {
-	$result = $obj >= $n;
+	$result = $obj->value >= $n;
 }

How to ignore this error #

You can use the identifier greaterOrEqual.invalid to ignore this error using a comment:

// @phpstan-ignore greaterOrEqual.invalid
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: greaterOrEqual.invalid
