How to solve "Fatal error: Class 'MySQLi' not found"?

Question

I'm doing a tutorial and got this error: Fatal error: Class 'MySQLi' not found (long URL) on line 8 The code on line 8 is: $mysqli=newMySQLi($db_server,$db_user,$db_pass,$db_name) ;I saw someone online saying to see if it was turned on in my phpinfo(), but there was nothing listed under "mysqli". Also, I'm running PHP version 5.2.5

You can check whether the mysqli library exists by executing the following code:

if (!function_exists('mysqli_init') && !extension_loaded('mysqli')) {
    echo 'We don\'t have mysqli!!!';
} else {
    echo 'Phew we have it!';
}

Sounds like you just need to install MySQLi.

If you think you've done this and are still having issues, please post your operating system and anything else that might help with further diagnosis.
