1.mysql_query()
2.别用mysql_connect了,php.net mysql_connect

Note:
本扩展自 PHP 5.5.0 起已废弃,并在将来会被移除。应使用 MySQLi 或 PDO_MySQL 扩展来替换之。参见 MySQL:选择 API 指南以及相关 FAQ 以获取更多信息。用以替代本函数的有:

<code>mysqli_connect()
PDO::__construct()
</code>

mysql_query(),不是mssql_query()你没有定义mssql_query()当然无法调用。

<code>Call to undefined function mssql_query()?</code>

调用未定义的函数报错,应改为mysql_query()

哥哥,你截图的是mysql,函数却调用mssql,后者是sqlserver的
