same for

phpstan-src/resources/functionMap.php

Lines 11780 to 11783 in d1e0b1b

	'strnatcasecmp' => ['int', 's1'=>'string', 's2'=>'string'],
	'strnatcmp' => ['int', 's1'=>'string', 's2'=>'string'],
	'strncasecmp' => ['int', 'str1'=>'string', 'str2'=>'string', 'len'=>'int'],
	'strncmp' => ['int', 'str1'=>'string', 'str2'=>'string', 'len'=>'int'],

?

maybe also substr_compare

additionally a test-case regarding your reported error would be great.
