简单实用socket

czk

@socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>10, "usec"=>0));当socket_read得不到响应，这里设置时间可以跳过不会陷入死循环
现在socket读写数据的流程是这样的：
0 H, D/ N) F" p, m
7 L' e: U: ~  o' W' D$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
& I. ]+ E* Z" I/ _7 t! E& Q
- ^) I$ A5 K  Msocket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

socket_connect($socket, IP, PORT);

socket_write($socket, $strxml, strlen($strxml);
$back = socket_read($socket, 8192);
# E- y7 q; P$ ^. h% w+ [' c8 a  F9 W: m
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？
) d! S" n$ I1 ?) P" q8 Wsocket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
6 a- X; u. Z  }4 z1 R9 bsocket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
