This may be common knowledge for those of you more experienced with PHP out there, however I racked my brain trying to figure out why my php scripts werent working correctly with my XHTML pages. Which is why I stopped learning PHP for a while. (Just starting now actually :-p)
So for those of you who are having trouble as well using XHTML with PHP, I present to you a short tutorial to make sure they work correctly together.

The problem is the very first line in a XHTML page.

Using that in conjunction with your php includes, or other php code causes the page to error because PHP thinks that the <?xml... tag is PHP as well.

To fix:
Open your php.ini file and look for:

and change it to:


Save and close it. Now in order to use php code; you must start with <?php... instead of the short tag <?...
However you should now be able to use PHP and XHTML together flawlessly.

Heh I wanted to start learning PHP for some time, and I bet if i would have done it, I would've got stuck on this matter. Tnx for explaining this, it probably saved up a lot of my time.


By the way, since I'm such a PHP noob, could you explain a bit of the concept of working with includes? What are PHP includes exactly and how do I use them (or do they just reffer to including external php files to your HTML code)?

Also, do you know anything about SSi (Server Side Includes). I got advice from a lot of ppl to start using SSi for my websites, but none of them could explain the concept (see, they were just using templates that had SSI withing them).

Tnxy and sorry for the bother.

You're welcome. Im glad it helped a bit, as I hope it helps others having the same problem.

Php includes can be used for many things. I use them for navigation, instead of writing links over and over and over again in each and every html/xhtml page. You can write them once and include them using php includes. More information can be gained from the tutorials found here:

As for SSI includes I have absolutely no idea about. Sorry Perhaps those are somehwere around the tutorial database as well.

Tnxy

Nothing about SSI includes, but I guess I'll have to start learning my php anywayz

You've been of great help. tnx

Not a problem. Glad I could help in some way.

This probably doesnt affect as <?xml does not equal <?

Perhaps, but <?xml was causing an error for me, causing my php scripts to not function. However when I turned short_open_tags off everything went smoothly.

Cliff, it does, the first sign of <? tells php that it want's to start a script

This fixes it, if you've read the tutorial above And I think raenef means PHP and XML as opposed to XHTML
