@socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>10, "usec"=>0));当socket_read得不到响应，这里设置时间可以跳过不会陷入死循环
* x! z6 m4 J# R0 s' |3 o现在socket读写数据的流程是这样的：
0 q/ \7 G3 ] n
) {: v( \: [. Z, y4 n$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
& \4 l, E9 O, s0 r/ s; `- Q% y- n `3 n: j
socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

socket_connect($socket, IP, PORT);
. K7 v1 b8 D1 `
. q. C$ z% x5 nsocket_write($socket, $strxml, strlen($strxml);& R4 X, [2 Q" D: G _# j% g
$back = socket_read($socket, 8192);/ R/ d' {: c1 s
& c$ B) \( a( { A
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？
