Probably a quick procedure to doing the following.

I'm trying to protect my source code, and I was looking over at eBay's website, how they use a eBay.dll file to access their web functions.

Right now, I have 1 file, index.php which contains all my page functions. I want to be able to store all this into a .dll file, and have it run from my web server. What is the procedure for doing this?

I don't believe you can turn your page into a dll in PHP. To do so would require a PHP Compiler.

If you want to protect your source code, I'd recommend looking into other solutions such as the Zend Encoder, or IonCube Encoder.

There are a few others too, but I'd recommend using one of the above.

Zend Costs more, but gives you more obscure code, that is extremely difficult(much more difficult than DLL's) to reverse engineer.

If you do want to make a DLL, you'll have to code it in C, using the Zend API.

You missed the point. Dlls have nothing to do with PHP, they are usually written in c++. You can, however, precompile/obfuscate your source code.
The best one is surely the Zend Optimizer, but its license cost is very very high. There are cheaper ones, still commercial and good software, like www.ioncube.com
There are at the end, free php obfuscating tools, but those i checked out are not much worthy. Please let me know if you find something free working well.

If you really want to make DLL Files to use with PHP, check out the http://www.zend.com/apidoc/

Bare in mind however that you will not be able to make DLL's in PHP itself yet.

One package I forgot about was bcompiler.

I believe it will only work with classes however.

Check out http://pecl.php.net/package/bcompiler

bcompiler is free. Any other product that encodes PHP into a way that it can't be reversed, costs money AFAIK.

You need to write them in c. You can find plenty of examples in the php distribution, under the ext/ directory.

Hi darkarnoir

Thanks for the accepting my comment regarding bcompiler, as assisted, but I can't figure out how you consider ThG's first post(which you accepted as "Accepted Answer" to be more helpful than my first post.

From what I can see they contain the exact same information(and the exact same suggestions), except that mine was posted two minutes before hand.
