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);

) n5 D- I8 l& C7 T% ]6 ]8 h  Qsocket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );
' A$ x$ ?  H4 _7 f
socket_connect($socket, IP, PORT);

socket_write($socket, $strxml, strlen($strxml);
$back = socket_read($socket, 8192);
- ^. S% u( v3 {( T8 j9 Y- J
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？
% n6 w9 a& s' h7 fsocket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO,array("sec"=>3, "usec"=>0));//接受超时
4 T1 D. s9 y! W/ W1 t* r( V) lsocket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO,array("sec"=>2, "usec"=>0));//发送超时
