推荐答案

您升级到 PHP 7，现在 mysql_connect 已弃用.检查你的:

You upgraded to PHP 7, and now mysql_connect is deprecated. Check yours with:

php -version

将其更改为 mysqli_connect 如下:

$host = "127.0.0.1";
$username = "root";
$pass = "foobar";
$con = mysqli_connect($host, $username, $pass, "your_database");

如果您要升级旧版 PHP，现在您面临的任务是使用 mysqli_* 函数升级所有 mysql_* 函数.

If you're upgrading legacy PHP, now you're faced with the task of upgrading all your mysql_* functions with mysqli_* functions.
