在pear的Net_Ping中，如何将获取的ping信息提取出来？

<?php

require_once 'Net/Ping.php' ;

$ping = new Net_Ping;
$ping->setArgs(array("count" => 5,
                     "size"  => 32,
                     "ttl"   => 512
                    )
              );      
var_dump($ping->ping("10.44.98.20");

?>

执行以上代码,返回以下信息:

object(Net_Ping_Result)#2 (11) { ["_icmp_sequence"]=> array(2) { [0]=> int(1533) [1]=> int(73 } ["_target_ip"]=> string(2) "it" ["_bytes_per_request"]=> int(0) ["_bytes_total"]=> int(0) ["_ttl"]=> int(61) ["_raw_data"]=> array(10) { [0]=> string(0) "" [1]=> string(42) "inging 10.44.98.20 with 32 bytes of data:" [2]=> string(0) "" [3]=> string(51) "Reply from 10.44.98.20: bytes=32 time=1533ms TTL=61" [4]=> string(50) "Reply from 10.44.98.20: bytes=32 time=738ms TTL=61" [5]=> string(0) "" [6]=> string(32) "ing statistics for 10.44.98.20:" [7]=> string(56) " Packets: Sent = 2, Received = 2, Lost = 0 (0% loss)," [8]=> string(46) "Approximate round trip times in milli-seconds:" [9]=> string(55) " Minimum = 738ms, Maximum = 1533ms, Average = 1135ms" } ["_sysname"]=> string(7) "windows" ["_round_trip"]=> array(3) { ["min"]=> int(73 ["max"]=> int(1533) ["avg"]=> int(1135) } ["_transmitted"]=> int(2) ["_received"]=> int(2) ["_loss"]=> int(0) }

如何才能将上面的信息按我需要的值如Sent包,Received包, Lost值,  time,TTL提取出来?不是从返回的信息中取,而是从ping的函数中取。请指教。。。

ping.php如下：
require_once "EAR.php";
require_once "OS/Guess.php";
