/* Prototype: array explode ( string $delimiter, string $string [, int $limit] );
   Description: Returns an array of strings, each of which is a substring of string 
                formed by splitting it on boundaries formed by the string delimiter.
                If limit is set, the returned array will contain a maximum of limit 
                elements with the last element containing the rest of string.
