美好的一天。请告诉我如何修复连接到Mysql的错误?
Warning: mysqli_select_db() expects exactly 2 parameters, 1 given in /home/user/db.php on line 7
Warning: mysqli_error() expects parameter 1 to be mysqli, string given in /home/user/db.php on line 7
脚本看起来像这样
mysqli_connect("localhost", "user", "pass") or die (mysqli_error ());
mysqli_select_db("db_name") or die(mysqli_error());
如果不连接php.ini,一切正常,如果我连接(它现在为空),有一个错误。在服务器上的PHP 5.5,共享主机。

连接也必须在mysqli_select_db()
:
$con = mysqli_connect("localhost", "user", "pass") or die(mysqli_connect_error());
mysqli_select_db($con, "db_name") or die(mysqli_error($con));

尝试这样的事情:
$conn = mysqli_connect("localhost", "user", "pass") or die (mysqli_error ());
mysqli_select_db("db_name", $conn) or die(mysqli_error());
