我将如何使用PHP连接到mysql数据库？

Question

I have read that PHP is obsoleting the MySql functions.

How will we connect to MySql database?

Answer 1

Where did you hear that? I think it would be a great idea, but it's news to me.

It's better to use new mysqli('hostname', 'username', 'password', 'database')

Or (even better) use new PDO('mysql:dbname=database;host=hostname', 'username', 'password')

Answer 2

使用新的MySQLi类。

Answer 3

The new, better way of doing it is to use PDO. You can find pretty of examples on the web if you Google for "php mysql pdo" , here is one .

Answer 4

Using PDO (PHP Data Objects)

example.

$dsn = 'mysql:dbname=testdb;host=127.0.0.1';
$user = 'dbuser';
$password = 'dbpass';

try {
    $dbh = new PDO($dsn, $user, $password);
}
catch (PDOException $e) {
    echo 'Connection failed: ' . $e->getMessage();
}
