Code Quality: Replace is_integer() with is_int() for consistency.

[https://www.php.net/manual/en/function.is-integer.php is_integer()] is an alias for [https://www.php.net/manual/en/function.is-int.php is_int()]. While they function identically, the WordPress Coding Standards and modern PHP practices generally lean towards using the official function name rather than its alias to maintain consistency across the codebase.
