的mysql-擴展__deprecated和PHP7 removed__。除非您使用一些遺留代碼 - 關於'mysql'的__forget__，否則請參閱上面的註釋。 –

嘗試使用mysqli_connect（）而不是mysql_connect（）語句。它是mysql的改進版本。

mysql函數已經在PHP7 XAMPP中被刪除所以，請使用PDO或My_Sqli來避免這種情況。

PDO will work on 12 different database systems, where as MySQLi will only work with MySQL databases.

PDO：https://www.w3schools.com/php/php_mysql_connect.asp

MY_Sqli：https://www.w3schools.com/php/php_mysql_connect.asp

注：

mysql_connect — Open a connection to a MySQL Server Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used.
