What does the .functions.inc.php file do?

Hi Guys,

I'm a newbie at PHP so I asked a guy to do some PHP code changes on my website. Today I found the above file on my html_public directory area on my website? I have changed the passwords not to allow him back on... but I need someone to tell me what this file does?

It looks like a Sitemap Creator, why would he do this?

 

I assume that .functions.inc.php will contain functions that are being used across your site. The file is then simply included and all functions are available thus saving time to have rewrite them or coy and paste them.

Without posting the file online it is impossible to see what the file does.

Sitemaps are very useful for search engines.

What changes did you ask him to make?

 

Here is the file...

All I asked the guy to do is to make users enter more information to register on my website. But for some unknown reason, even though he's made the changes he's also put this file in the public area of my website. I didn't ask for it but its there.

 

Why don't you ask him?

 

I have and he's not responded.... so I'm think it something suspicios?!

 

It really doesn't look suspicious (then again, I haven't closely read every line). I think he probably just included it by accident or out of habit.

 

Thanks for the input SmallPotatoes and stephan2307.

I've had other suggestions that he may have put this script in to get all the emails of your users who've registerd. But then I don't quite see how in the script above when the emails are in a mysql database.
