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：

  q' `" n; `2 w$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
1 O, k' M: c8 n8 S, p6 z8 L) ?" C
/ R0 X& w- i: N( C; H- `- |2 S- O4 ]socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

socket_connect($socket, IP, PORT);
  [( P7 r4 ^; a
% [7 P8 y2 e4 g, ], g9 X  Q0 hsocket_write($socket, $strxml, strlen($strxml);
) w+ K! c& P5 g' p$back = socket_read($socket, 8192);

: Z- B, A$ N& [2 _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($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
4 S* ~; O& V4 d; g. `3 [socket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
