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
8 Q, I4 K9 ?% r现在socket读写数据的流程是这样的：

' j- E- N  i8 `' K1 j9 J$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

! R1 m' C: l' c2 X% r: I2 k$ Y# Esocket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );
7 r/ ]! [( b$ P+ w
; A4 j4 ^6 V# O* Q  Tsocket_connect($socket, IP, PORT);
: F/ h  {6 i+ J# L& E: `
  Q" Q# [3 }! h; z7 L' [/ lsocket_write($socket, $strxml, strlen($strxml);
- d. x" l' m4 ~- E$back = socket_read($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？
