php中三種資料庫的串連方式

// mysqli$mysqli = new mysqli("example.com", "user", "password", "database");$result = $mysqli->query("SELECT 'Hello, dear MySQL user!' AS _message FROM DUAL");$row = $result->fetch_assoc();echo htmlentities($row['_message']);// PDO$pdo = new PDO('mysql:host=example.com;dbname=database', 'user', 'password');$statement = $pdo->query("SELECT 'Hello, dear MySQL user!' AS _message FROM DUAL");$row = $statement->fetch(PDO::FETCH_ASSOC);echo htmlentities($row['_message']);// mysql$c = mysql_connect("example.com", "user", "password");mysql_select_db("database");$result = mysql_query("SELECT 'Hello, dear MySQL user!' AS _message FROM DUAL");$row = mysql_fetch_assoc($result);echo htmlentities($row['_message'])
