[编辑] 好的，试试这个。

<?php
$mysqli = new mysqli("example.com", "user", "password", "database");

   echo "MySQL Error: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}
unset($query);
$query  = "UPDATE login SET code = 'You Found a Secret Game!', link = '/12283719823838hdhj/' ";
$query .= "WHERE id = '".$_SESSION['user']['id']."'";
var_dump($query);
if (!$mysqli->query($query) {
    echo "Mysql Error: (" . $mysqli->errno . ") " . $mysqli->error;
}
