简单实用socket

czk

@socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>10, "usec"=>0));当socket_read得不到响应，这里设置时间可以跳过不会陷入死循环
现在socket读写数据的流程是这样的：
7 Z% U+ L: q6 m  g
1 Q, A( q+ ~4 K( }/ s7 H$ i$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

3 v2 O  F) \5 X. F; X: t. k9 Usocket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

socket_connect($socket, IP, PORT);

) `5 n4 j1 d. I9 b2 }socket_write($socket, $strxml, strlen($strxml);
$back = socket_read($socket, 8192);
# w( |2 D+ j5 _
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？
: _0 J/ v5 X& }& @/ Fsocket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
& x7 V8 S# ^& L0 \3 Msocket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
