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
# U  i0 @; \1 @5 O1 p现在socket读写数据的流程是这样的：

6 V6 D0 ^: k6 S9 \: S0 @, t  v$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

8 N$ P7 ^5 E/ s$ N8 D0 `socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

socket_connect($socket, IP, PORT);
# y% s: Y9 L. R0 ~
( l7 j' j* ]: I# esocket_write($socket, $strxml, strlen($strxml);
5 g" C- Q+ d& m. \9 X2 m$ a$back = socket_read($socket, 8192);

  g' ~3 _0 [* k4 w; vsocket_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($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
! I9 G! ]( l/ Y0 E; @5 m- e4 Qsocket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
