Urmez un tutorial despre baza date si incerc sa fac o baza de date cum este in tutorial dar imi apare eroarea respectiva din imagine.
Sistemul de operare folosit este Windows 10(xampp) si cel din tutorial este Mac.

Am mai avut o eroare in legatura cu baza de date.

Am citit pe internet ca cei care au XAMPP si versiunea a 7 al PHP-ului mysql se inlocuieste cu mysqli si am inlocuit peste tot si la error si tot imi da eroare.

Fatal error: Uncaught Error: Call to undefined function mysql_connect() in C:\xampp\htdocs\php_sandbox\databases.php:2 Stack trace: #0 {main} thrown in C:\xampp\htdocs\php_sandbox\databases.php on line 2

Eroarea este datorata faptului ca folosesti o functie pe care nu o gaseste. Daca tot vrei sa folosesti mysqli, atunci in loc de mysql_query, foloseste mysqli_query

Ce iti recomand eu, in loc sa adaugi informatii sensibile de conectare la mysql in fiecare fisier, mai bine folosesti un require.
Concret:
1. creaza un fisier denumit dbconnect.php, iar in el scrie asta:

$servername = "localhost"; //de obicei este localhost, doar daca faci remote sql pui IP-ul serverului de SQL
$username = "unuser"; // username baza de date
$password = "oparola"; // parola username
$dbname = "example"; //baza de date
// Creare conexiune
$conn = new mysqli($servername, $username, $password, $dbname);
// Verificam conexiunea
if ($conn->connect_error) {
die("Conexiune esuata: " . $conn->connect_error);
}

2. la inceputul fisierului, dupa tagul <?php adauga asa:

require_once 'dbconnect.php';

3. Orice query il rulezi asa apeland conexiunea la baza de date:

$testquery = "SELECT * FROM users";
if ($result = mysqli_query($conn, $testquery)) {
if (mysqli_num_rows($result) > 0) {
	 while ($row = mysqli_fetch_array($result)) {
		 $userName = $row['userName'];
		 echo $userName;
	 }
}
else { echo "No result found"; }
}
