Class 'mysqli' not found

[Gruszek]

Hello,
I have installed XAMPP with PHP 7.0.2 and i get this error:

Fatal error: Uncaught Error: Class 'mysqli' not found in C:\strona\htdocs\scripts\connection.php:2 Stack trace: #0 C:\strona\htdocs\pages\login.php(2): require_once() #1 {main} thrown in C:\strona\htdocs\scripts\connection.php on line 2

login.php
<?php
require_once("../scripts/connection.php");
?>

connection.php
<?php
$db = new mysqli("localhost", "root", "", "baza");
?>

What is wrong?
In php.ini i have unmarked:
extension=php_mysql.dll
extension=php_mysqli.dll
Regards.

Hi,

Are you using one of the portable versions?
If yes, it seems that the php.ini configuration of this versions is incomplete.
The extension folder is not set, extensions are not enavled, tmp path is not set, etc.
In the current state i cannot recommend to use the portable versions except you are knowing exactly how to configure php.

best wishes,
Altrea

I have installed this: xampp-win32-7.0.2-1-VC14-installer.exe
I try change xampp version and i get the same error.
On version xampp-win32-5.6.15-1-VC11 error looks like this:

Fatal error: Class 'mysqli' not found in C:\strona\htdocs\scripts\connection.php on line 2

Hi,

i'm using xampp-portable-win32-7.0.2-1-VC14.zip and i solve this problem modifing php.ini adding path to PEAR folder
include_path = ".;<path to PHP PEAR folder>"

I discover this trick comparing an old php.ini with the new one.
In my opinion, XAMPP portable setup doesn't update php.ini properly.

Regards.
