Test ksort() function : basic functionality

<?php
/* Prototype : bool ksort ( array &$array [, int $sort_flags] )
* Description: Sort an array by key, maintaining key to data correlation
* Source code: ext/standard/array.c
*/
/*
* Testing ksort() by providing array of integer/string values to check the basic functionality with following flag values :
* 1.flag value as defualt
* 2.SORT_REGULAR - compare items normally
* 3.SORT_NUMERIC - compare items numerically
* 4.SORT_STRING - compare items as strings
