mysql_connect（）致命错误

Question

我有一个问题，当我写welcome.php时我需要使用mysql_connect()但是当我运行它时会出现错误：

 Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /home/u781677053/public_html/cas/welcome.php:4 Stack trace: #0 {main} thrown in /home/u781677053/public_html/cas/welcome.php on line 4

我正在使用一个名为Hostinger.es的网站，而不是apache或任何东西

代码：

mysql_connect("localhost","u781677053_lo","987654") or die();
mysql_select_db("u781677053_po") or die();

Answer 1

mysql_*现已弃用。使用mysqli_*或PDO

您可以在mysqli_*中执行以下操作： -

$connect = mysqli_connect("localhost","u781677053_lo","987654","u781677053_po") or die(mysqli_connect_error());
