请问能否在网页中播放警报声?
比如我添加了一个变量$AlarmThreshold,当它超过某个阈值时自动播放该声音?这样怎么弄好呢?是不是要添加一个flash之类的呢?求方法。

------解决方案--------------------
php不能说话的。。要用flash或html的媒体标签
------解决方案--------------------
那你总得也要跟前端交互才行啊。

最终还是要js去触发
------解决方案--------------------
这要用js控制,可以用PHP在页面放一个判断值,用js获取其中的value,然后再输出报警声:

JScript code
<script><?php    if(!empty($alarmList)){ ?>                //这里的src指向声音文件        $("#music").html('<embed id = "soundControl1"  src = "./style/baojing.mp3"  mastersound hidden = "true"  loop ="true"  autostart = "true">');    <?php }else{ ?>        $("#music").html("");?></script><div id="music"></div><div class="clear">
                 
              
              
        
            </div>
