php - Uncaught Error: Call to undefined function mysql_connect()

Uncaught Error: Call to undefined function mysql_connect() in C:\xampp\htdocs\phoenixproject\register.php:9 Stack trace: #0 {main} thrown in C:\xampp\htdocs\phoenixproject\register.php on line 9

How to solve this??

Answer

It is most likely MySql extensions are not being loaded. Open your php.ini file and check if extension=php_mysql.dll and extension=php_mysqli.dll is uncommented
