简单实用socket

@socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>10, "usec"=>0));当socket_read得不到响应，这里设置时间可以跳过不会陷入死循环
" k$ c) S3 H* Q现在socket读写数据的流程是这样的：

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

% Q* B8 T+ _+ T, Ysocket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

  O% C& Y3 t) I  J, x) ]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($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
socket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
