I am doing a tutorial and am getting this error:

Fatal error: Class 'MySQLi' not found (LONG URL) on line 8

The code on line 8 is:

$mysqli = new MySQLi($db_server, $db_user, $db_pass, $db_name);

I saw online someone said to see if it was turned on in my phpinfo(), but there wasn't anything listed in there under for "mysqli".

Also, I am running PHP version 5.2.5



Sounds like you just need to install MySQLi.

If you think you've done that and still have a problem, please post your operating system and anything else that might help diagnose it further.

Replace this include './connection.php'; to include 'connection.php';
Replace you class name connection to Connection

Code should be


    #FileName = "Connection_php_mysql.htm"
    #Type = "MYSQL"
    #HTTP = "true"

    $hostname_Main_DB = "localhost";
    $database_Main_DB = "mydb";
    $username_Main_DB = "root";
    $password_Main_DB = "";

    $con = mysqli_connect($hostname_Main_DB,$username_Main_DB,$password_Main_DB, $database_Main_DB) or die ( "Failed to connect to MySQL: " . mysqli_connect_errno());

    $db=mysqli_select_db($database_Main_DB,$con) or die( "Failed to connect to MySQL: ".mysqli_connect_errno());

You should remove "new". For more information read this

Edit :-

Also you have added . in between two variable that should be ,

$username_Main_DB. $password_Main_DB replace this with $username_Main_DB,$password_Main_DB

yo need create the user "pma" in mysql or change this lines(user and password for mysql):

/* User for advanced features */
$cfg['Servers'][$i]['controluser'] = 'pma'; 
$cfg['Servers'][$i]['controlpass'] = '';

Linux: /etc/phpmyadmin/

This is how your code should look (with added SQL Injection protection):

include "dbinfo.php"; //contains mysqli_connect information (the $mysqli variable)
$name = mysqli_real_escape_string($_GET['name']);
$text = mysqli_real_escape_string($_GET['text']);

$sqlqr = "INSERT INTO `ncool`.`coolbits_table` (`name`, `text`, `date`) VALUES ('" . $name . "', '" . $text . "', CURRENT_TIMESTAMP);";

mysqli_query($mysqli,$sqlqr); //function where the magic happens.

Take a look at what I've done. Firstly I've escaped the user input you're retrieving into the $name and $text variables (this is pretty much a must for security reasons) and as others have suggested you should preferably be using prepared statements.

The problem is that you weren't surrounding string values with single quotes ('), which is a requirement of the SQL syntax.

I hope this helps to answer your question.
