i am getting an error during a php execution which i think it was due to a newer php 5.5 thing.
我在 php 执行过程中遇到错误，我认为这是由于更新的 php 5.5 问题。
Deprecated:
mysql_pconnect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in /public_html/mydomain.com/connx.php on line 7

mysql_pconnect()不推荐使用 mysql 扩展并将在将来删除：在

检查中，在 /public_html/mydomain.com/connx.php 中使用 mysqli 或 PDO 代替
The inner code looks this way
内部代码看起来像这样
So i thought changing the mysqlto mysqlicould solve the issue :
所以我认为改变mysqltomysqli可以解决问题：
$conn = mysqli_pconnect($hostname_conn, $username_conn, $password_conn) or trigger_error("Server Down");
And instead, I'm getting this error... so i guess it was not the correct way of doing so :)
相反，我收到了这个错误……所以我想这不是正确的做法:)
Fatal error: Call to undefined function
mysqli_pconnect()
致命错误：调用未定义的函数
mysqli_pconnect()
anyhow i can fix this issue ? The code was built long time ago and now i cant really get in touch with him :x
无论如何我可以解决这个问题？该代码是很久以前构建的，现在我无法真正与他取得联系：x
thanks ** UPDATED ** I changed the mysqli_connect and when i load the php script... it shows few errors now... just wondering do i have to change these syntax too ?
谢谢 ** 更新 ** 我更改了 mysqli_connect，当我加载 php 脚本时...它现在显示的错误很少...只是想知道我是否也必须更改这些语法？
mysql_select_db($database_conn);
mysql_query("SET NAMES UTF8");

See the documentation for mysql_pconnect:
Alternatives to this function include:
mysqli_connect()with p: host prefix
此功能的替代方案包括：
mysqli_connect()带 p：主机前缀
So use mysqli_connect, not mysqli_pconnectand modify the host argument as described
所以使用mysqli_connect, notmysqli_pconnect并按照描述修改主机参数

There is no "mysqli_pconnect", but you can make persistent connections using mysqli_connect()by adding p:to the beginning of the hostname.
没有“mysqli_pconnect”，但您可以mysqli_connect()通过添加p:到主机名的开头来建立持久连接。
So you can restore the old style by adding this to the head of your php file:
因此，您可以通过将其添加到 php 文件的头部来恢复旧样式：
if (!function_exists("mysql_pconnect")){
function mysql_pconnect($host, $username, $password){
return mysqli_connect("p:".$host, $username, $password);
}
}
UPDATE: As pconnects have nearly no benefit, you should replace mysql_pconnectwith mysql_connectin your scripts anyway.
更新：由于 pconnects 几乎没有任何好处，因此无论如何您都应该在脚本中替换mysql_pconnectwith mysql_connect。

There is no mysqli_pconnect(), but you can make persistent connections using mysqli_connect()as described in the manual, simply by adding p:to the beginning of the hostname.
没有mysqli_pconnect()，但你可以使用永久连接mysqli_connect()的手册中描述，只需添加p:到主机名的开头。
Quote from the manual:
引用手册：
Prepending host by p: opens a persistent connection.
Prepending host by p: opens a persistent connection.
