making a bell sound?

I have a php script which autoloads every minute to display txt msgs out of a database. I want to add a sound if there is a new msg in the database - so my question is: how do I make a sound in php? I have a .wav file of the sound I want to use. Thanks

Find an MP3 "ding" file ... perhaps the name of the file will be "ding.mp3" ...

Then try this:

echo"<embed src='ding.mp3' autostart='true' hidden='true' id='sound1' loop='false'></embed>\n";
