Fatal error: Call to undefined function mysqli_connect()

I get the error message:

Fatal error: Call to undefined function mysqli_connect() in /home/reward/public_html/include/db/Db_connection.php on line 42

Code (markup):

Basically, I edited a file called 'config.php' with the database information but for some reason it generates that error line.

Could anyone please help me out?

Would be greatly appreciated.

 

create a php file with the following content

<?php
phpinfo();
?>

PHP:

Run the file. See if mysqli is included in your PHP installation. If it's not you'll have to recompile php with mysqli included (on Linux) or include the dll in php.ini (in Windows).

 

Have you defining your database name, username, and password for your dbase?

 

this mean you have not installed "mysqli" extension for PHP

 

install mysqli for PHP and configure database username, password, hostname etc.
