使用PHP

Question

mysql表的输出为

mysql> desc alienvault_siem.po_acid_event;
+------------+------------------+------+-----+------------------+-------+

12 rows in set (0.00 sec)

我对src_host感兴趣。在php中，我的代码如下： .....

$sqlgraph       = "select count(distinct plugin_id, plugin_sid) as num_events,ip_src, hex(src_host) as name from alienvault_siem.po_acid_event AS acid_event WHERE 1=1 $query_where group by name having ip_src>0x00000000000000000000000000000000 order by num_events desc limit $limit";

        $rg = $conn->CacheExecute($sqlgraph);


        if (!$rg)
        {
            print $conn->ErrorMsg();
        } 
        else 
        {
            while (!$rg->EOF) 
            {

                $data[]  = $rg->fields["num_events"];
                $label[] = $rg->fields["name"];

                $links[] = $forensic_link . '&ip_addr[0][0]=+&ip_addr[0][1]=ip_src&ip_addr[0][2]=%3D&ip_addr[0][3]=' . inet_ntop($rg->fields["name"]) . '&ip_addr[0][8]=+&ip_addr[0][9]=+&ip_addr_cnt=1';

                $rg->MoveNext();
            }
        }

        $colors = get_widget_colors(count($data));

        break;

网页上的输出看起来像我可以看到32长度的十六进制字符串

实际上src_host包含例如

  

alienvault

我想知道如何将其显示为asci字符串，而不是十六进制十进制或二进制。谢谢
