我有一台装有Linux CentOS发行版的机器，同时具有多个互联网连接。

我正在尝试编写一些将执行以下操作的PHP代码:

通过特定的Internet连接执行对特定URL“例如google.com”的HTTP请求。

同时对多个Internet连接执行上述操作(这意味着将运行多个进程，每个进程都通过特定连接进行HTTP请求)。

请注意，互联网连接为ppp0，ppp1和ppp2。

这是“ifconfig”的输出:

这是route命令的输出:

任何有任何想法如何工作的人吗？

最佳答案

您可以使用curl_multi_*()和curl_setopt(CURLOPT_INTERFACE, 'ppp0')等在PHP中执行此操作。

就实际发现接口而言，我只是对ifconfig的输出运行了一个简单的正则表达式。当然，这不是一种很好的处理方法，但是在脚本启动时，您通常只需要执行一次，因此，这并不是一个巨大的性能问题。
