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
  k% Y5 k  a& d8 x/ N现在socket读写数据的流程是这样的：

# X% E9 l6 D, Q  G$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
/ g+ ~1 }6 w& d$ v3 I3 x0 h
! s- c5 @% r6 x  f, Rsocket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

+ y  T' o( y1 q) E7 ~! asocket_connect($socket, IP, PORT);

socket_write($socket, $strxml, strlen($strxml);
; T  I. ?/ x6 }8 E  B8 @, h9 f$back = socket_read($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($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
socket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
