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

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
* _2 }8 M8 S2 K% g; Q) x! Z

socket_write($socket, $strxml, strlen($strxml);

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
