推荐答案

您已在 mysql_connect（）中使用了代码。如果您的PHP版本为7或更高版本，则由于已弃用，因此将不起作用（将适用于5.5和5.6版本，但会出现警告）。

You have used mysql_connect() in the update clause of the code. If your PHP version is 7 and above it will not work (will work for 5.5 and 5.6 versions but with a warning) as it is deprecated.

警告

Warning

此扩展在PHP 5.5.0中已弃用，在PHP
7.0.0中已删除。相反，应使用MySQLi或PDO_MySQL扩展。另请参阅MySQL：选择API指南和相关的FAQ，以获取更多
信息。此功能的替代方案包括：

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. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

mysqli_connect()
PDO::__construct()

在编辑时，我看不出在建立新连接时的意义在脚本开头建立了数据库连接。使用与从脚本向数据库中插入数据相同的函数：

I don't see the point in establishing a new connection while editing when there is a database connection that was made in the beginning of the script. Use the same functions used to insert data to the database from your script:

$db->query("UPDATE tablename SET column_name = value");
// to check no. of rows affected by the previous query 
$db->affected_rows()
