Automatically reloading a php page

Hello, I am not sure if this question is appropriate for this list, and if it isn't, I apologize. My question has to do with reloading a php page. I have a php page which displays mysql data. However, there will constantly be new mysql data being displayed. The new data shows up on the php page without a problem if I do a reload, but I need it to be done automatically. I tried to use the following html tag. <meta http-equiv="refresh" content=10:url=titles.php"> and definately refreshes the page, but won't display new data. If anybody knows how to get it to work, I would greatly appreicate any insight! Thanks in advance! Sincerely, Jero
