Answer 1

Uncomment the line extension=php_mysql.dll in your "php.ini" file and restart Apache. if its not working then update your xampp with latest version.

Answer 2

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:

mysqli_connect()

PDO::__construct()
use MySQLi or PDO

<?php
$con = mysqli_connect('localhost', 'username', 'password', 'database');

check this "Call to undefined function mysql_connect()" after upgrade to php-7
