Fatal error Call to undefined function mysql

 

This question already has an answer here:

  • Why shouldn't I use mysql_* functions in PHP? 14 answers

    • use mysqli_connect() instead of mysql_connect()

    mysql function is not suggest and it's already abandon

    Use mysqli_* functions. As you found mysql_* functions have been obsolete and even dropped in newer php.

    The new functions however differ that they get database connection as the first parameter. So the call should look like (or actually you can pass the db name as 4th parameter to mysqli_connect function): 

        mysqli_select_db($db, 'register')

    And the same for query etc.
