PHP Fatal error: Duplicate type null is redundant

[thomasschiet]

Since upgrading to PHP 8.2, I cannot mock SplFileObject.

Mockery::mock(SplFileObject::class, ['php://memory']);

This yields the following error:

PHP Fatal error:  Duplicate type null is redundant in /app/vendor/mockery/mockery/library/Mockery/Loader/EvalLoader.php(34) : eval()'d code on line 1174

In EvalLoader.php(34) : eval()'d code line 1174:
                                    
  Duplicate type null is redundant  
                                    

Happens on versions 1.5.1 and dev-master 3c3ca93.

The problem seems to be with the getChildren method on SplFileObject, which has the null standalone type since PHP 8.2.

The generated code is:

    public function getChildren(): null|null{
$argc = func_num_args();
$argv = func_get_args();
$ret = $this->_mockery_handleMethodCall(__FUNCTION__, $argv);
return $r

If others have the same issue, you can consider using a partial mock, this does not generate code for the affected method.

Mockery::mock(SplFileObject::class . '[isReadable,fgetcsv]', ['php://memory'])
