防止来自 fsockopen 的警告 [英] Preventing warnings from fsockopen

问题描述

我使用 fsockopen() 循环连接到多个服务器.

I use fsockopen() to connect to multiple servers in a loop.

但是有些服务器无效，我收到如下所示的 PHP 警告:

However some servers are not valid and I get PHP warnings like the one below:

Warning: fsockopen() [function.fsockopen]: php_network_getaddresses: getaddrinfo failed: The requested name is valid, but no data of the requested type was found

有没有办法防止这些警告.

Is there a way to prevent these warnings.

喜欢在尝试 fsockopen 之前检查服务器是否良好?

Like checking whether the server is good before trying to fsockopen it?

或者有其他更好的解决方案吗?

Or is there another or better solution for this?

推荐答案

使用 错误控制运算符并检查 fsockopen() 的结果以验证您的连接是否有效.

Use the error control operator and check the results of fsockopen() to verfiy you have a valid connection.

$rc = @fsockopen(...);
if (is_resource($rc))
{
   // do work
}
