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

( }- H8 S9 p0 H$ G" C" n
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
$ Z6 ?$ H9 }; E. ?
socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>60, "usec"=>0 ) );

socket_write($socket, $strxml, strlen($strxml);
/ m2 c3 M0 W* ?" @0 Q# @$back = socket_read($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？
socket_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
