俺だったらconfigファイル作ってパスを定数で宣言しておく。

config.php------------------------
define("DOCUMENT_ROOT", "ROOTのパス");
---------------------------------

about.php-------------------------
include_once("../../CONFIG/config.php");
include_once(DOCUMENT_ROOT."'LIBLARY/_array.php');
---------------------------------

index.php-------------------------
include_once("../CONFIG/config.php");
include_once(DOCUMENT_ROOT."LIBLARY/_array.php");
---------------------------------

_array.php-------------------------
include_once(DOCUMENT_ROOT."LIBLARY/error_code.php");
include_once(DOCUMENT_ROOT."LIBLARY/ARRAY/arrayFunction.php");
---------------------------------
