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：

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

7 `# T% k4 }* u5 o' u  @4 N' asocket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

9 K1 p$ }/ g( T2 Fsocket_connect($socket, IP, PORT);
3 ^' B; R( s% \2 v4 k8 P" ]
, Z' E7 c# h6 g+ |( g7 f+ ~% y) e4 [socket_write($socket, $strxml, strlen($strxml);
$back = socket_read($socket, 8192);

. Z% O; a$ e. Xsocket_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($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
4 q+ o0 j: M' ?socket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
" z" x: M9 b# b7 v1 b: B/ k! o
