A1- Accés a BD amb PHP (10h)

Connexió a BD amb PHP

La base de dades a utilitzar serà mysql que haureu d'instal·la en el servidor Web.

Per connectar-nos a BD podem utilitzar tres maneres:

• mysqli procedural
• mysqli object-oriented
• PDO (PHP Data Objects)

Mysqli Procedural

<?php
$servername = "localhost";
$username = "username";
$password = "password";

// Create connection
$conn = mysqli_connect($servername, $username, $password);

// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";
?>

Mysqli object-oriented

<?php
$servername = "localhost";
$username = "username";
$password = "password";

// Create connection
$conn = new mysqli($servername, $username, $password);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 
echo "Connected successfully";
?>
