Including files question

[Anon]

A friend of mine gave me some PHP code that lets u include HTML inside your php file, by changing the URL to index.php?action=contact or something like that, which works well.

But that consists of stuff that first check if the file exists etc etc.

The question is, can I include a file using PHP, somehow like SSI?
Thanks

yes. use include().

But it is always better to check wether a file exists before you include it, because if it does not exists, your website explodes.

Can u give me an example code?
Because the code I have is for use like:
www.lalala.com/index.php?page=games

I need to include more than one page.
Thanks
