简单实用socket

@socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>10, "usec"=>0));当socket_read得不到响应，这里设置时间可以跳过不会陷入死循环
) R" A) L; w3 Z现在socket读写数据的流程是这样的：

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

socket_write($socket, $strxml, strlen($strxml);
- f0 o2 y8 j, h5 g$ X* l$back = socket_read($socket, 8192);

socket_read有时候收不到返回数据，应该是超时了，如何修改超时时间？
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
' ~2 y( A# R* ]0 l. i( asocket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
