简单实用socket

@socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>10, "usec"=>0));当socket_read得不到响应，这里设置时间可以跳过不会陷入死循环
3 j- n$ |: q5 Y" T现在socket读写数据的流程是这样的：

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

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

' o* r1 R6 s1 Y9 S/ D8 Bsocket_connect($socket, IP, PORT);

  u8 l" O  F8 Lsocket_write($socket, $strxml, strlen($strxml);
& H' B. L* B6 L' ?! ?2 R- ~  x$back = socket_read($socket, 8192);

% [7 h$ A; u. R( X& D0 i7 L" B: ssocket_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($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
' o5 [% D: V+ q0 k, Osocket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
