简单实用socket

czk

@socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>10, "usec"=>0));当socket_read得不到响应，这里设置时间可以跳过不会陷入死循环
5 S& g/ C0 f  d: B$ U现在socket读写数据的流程是这样的：
% _: p' k/ b% u7 E( \' q7 T! ]
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

5 C5 j% y% O' @( T0 gsocket_connect($socket, IP, PORT);
; h+ |/ d% V& B% @$ ^# d0 e& U1 e
) Y/ C6 q! ]4 c/ z0 Wsocket_write($socket, $strxml, strlen($strxml);
  i& ^( k4 _9 w$ B% l$back = socket_read($socket, 8192);

/ }) M- |; Q' y* ]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？
- V$ z* ^1 U( ]5 T+ Y; v6 usocket_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
