Hi,

I have a basic knowlege of PHP and I recently learned the basics of sessions. I will be redesigning a clients site in the near future and I am wondering if it is a good idea to simply add "session_start();" at the top of every single page as a general rule of thumb even if that particular page will not be needing any session data.

What is the general theories on this approach? Is there a smarter way to do it?

Thank you

If you are going to be using similar code (eg session_start() and also code to handle the sessions on each page), you should use a require/include statement in each file..

The included file should contain what you need to do to check your sessions and build the main header and footer for the site.

This reduces a lot of code, and will make it easier for you to follow.

Just my bit

I agree with Chris. If your going to be doing anything in particular with the sessions before the actual page.... put that all into a file, and then include / require it into each page..

It will make changing something later a lot easier. It also saves copying and pasting. :-)

Thanks guys,

Is there ever a reason why you would NOT want to have it on every page? (via include file or whatever)

It seems like one of those "set it and forget it" things. Just make sure it gets in there and if you ever need it, it's there. Right?

Pretty much, if you have session_start() on the start of every page, that means you can do calls to functions etc that may use some session variables.

If you dont have it there, you could be forever trying to work out "why isnt it working?!?"

It has happened to me before :-$
