简单实用socket

czk

@socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>10, "usec"=>0));当socket_read得不到响应，这里设置时间可以跳过不会陷入死循环
现在socket读写数据的流程是这样的：
5 W' N% m- B+ J1 O6 g7 F9 x% A3 o* k
+ w: Z" {' H2 n$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

4 o; ]  b& y+ A1 O" Q  f' X* Gsocket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );
; f7 v+ j  H' M; C. H; o9 e2 V; K
* L7 ~# V0 e! p( C) m% Esocket_connect($socket, IP, PORT);
- V! q$ _0 V! q- u. r8 Z& O
" x9 t% L2 |8 ]3 T# Y& }0 Osocket_write($socket, $strxml, strlen($strxml);
- @- A  J4 z! [! P  h4 d  `$back = socket_read($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($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
1 }% |$ F# C. {; }socket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
