Unable to connect to the database.

This is clearly a problem with your mysqli extension as the error says mysql_init is undefined.

xampp\php\php.ini

PHP.INI

Code:

;;;;;;;;;;;;;;;;;;;;;;
; Dynamic Extensions ;
;;;;;;;;;;;;;;;;;;;;;;

;; if like this with a semi-colon
;extension=mysqli

;; remove the semi-colon
extension=mysqli

What did you Try? What did you Get? What did you Expect?
