无法连接到数据库

Question

我似乎无法连接到数据库。下面是我的代码和我的数据库的屏幕截图，我正在尝试连接到remem539_test2，但我一直收到“No DB”。所以我似乎可以连接，但它似乎无法找到数据库。有线索吗？

<?php
$db_host = "localhost";
$db_username = "remem539_test2";
$db_pass = "...";
$db_name = "remem539_test2";

@mysql_connect ("$db_host", "$db_username", "$db_pass") or die ("No Connection");
@mysql_select_db ("$db_name") or die ("No DB");

echo ("Succsess");

?>

My DB's http://www.remembertheprojector.com/php/db.tiff

试试这个

$db_host = "localhost";
$db_username = "remem539_test2";
$db_pass = "...";
$db_name = "remem539_test2";

// Create connection
$conn = new mysqli($db_host, $db_username, $db_pass, $db_name);

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