Test sort() function : basic functionality

Elements will be arranged from lowest to highest when this function has completed.
* Source code: ext/standard/array.c

* Testing sort() by providing arrays with default keys and assoc arrays

* flag value as defualt
* SORT_REGULAR - compare items normally
* SORT_NUMERIC - compare items numerically
* SORT_STRING - compare items as strings
