Orio, Thank you very much. That is exactly what I needed. Thank you for the fast response.

Hello, I have a string that I need to get the numbers out of. The string has both text, and numbers. I want to get rid of the letters, and only keep the numbers. Is this possible?? Please help. Thank you, Gary

i figured it out. I created a variable and gave it the data from $refpage = $_SERVER['HTTP_REFERER'];. Then on the other page i used that in the header("location: $refpage"); and it works. Thanks

is there a way to direct the users back to a previous page automatically. right now i use the header("Location: ......"); to direct them, but what I want is for them to go to the second to last page they were at before they got to this page. I tried [code] <script LANGUAGE="JavaScript" type="text/javascript">     <!--     history.back();     //--> </SCRIPT> [/code] But that only took me back to the very last page I was at. I want to go back 2 pages. Any ideas?

I have one im MySQL, it adds users when they log in(session created), however, if a user does not log off(session exit) they are never removed from the table. I have seen on several sites that they have some way of calculating how many users are currently on. I would like something like that.

How do I get a list of all current sessions? This would act as a list of members that are currently logged in. Please help
