使用mysqli扩展,建立数据库连接并选择数据库,示例代码如下。 ```php <?php $servername = "localhost"; $username = "username"; $password = "password"; $database = "database_name"; // Create connection $conn = new mysqli($servername, $username, $password, $database); ```
Write PHP code to insert data: use SQL statements to insert lost or found information into the database.
