Question

I have a database which contains the link to audio files. I am trying to play them one after the other using the HTML audio tag. Presently I am using PHP. My code –

    $sql = "SELECT * FROM table";
    $r = mysql_query($sql);

       while($row = mysql_fetch_array($r)) {
            $id = $row["audID"];                                                
            $audsq = "SELECT * FROM table2 WHERE id ='$id'";            
            $resultaud = mysql_query($audsq);

            //Here I want to write a code to clear div="test"

            PlayAud(resultaud);
            sleep(2);   ///Not Sure             
        }

I am passing the link to aud file for the html to load and in

 <?php
      PlayAud($res) {
          $raud = mysql_fetch_array($res); ?>
      <div id="test">
      <audio> ...  </audio>
      </div>
 <?php }?>

Can some one tell me if I am doing it right ? also each clip is of 2 seconds hence I need to wait in the while loop for 2 seconds. If there is any other way can you suggest me?

Thank You

You cannot clear a div from php. The reason is that php is running on the server, and the div is echoed out to the client, where it is unreachable by php.

A solution here could be to use Client side scripting (with JavaScript). You’d program a function, which replaces the audio tag or its contents, and it would probably be a good idea to implement some preloading-mechanism as well.
