Next: How to copy from windows clipboard using PHP

Hello!



I have a DLL witch I want to use in PHP.

This DLL file is Eztwain3.dll

It is possible running it on PHP?

I think I must create a special DLL (like php_Eztwain3.dll) to call
Eztwain3.dll and also php5ts.dll

Then I just need to add the next line on the php.ini:

extension= php_Eztwain3.dll

And put the php_Eztwain3.dll in the php\ext\ dir

Is that correct?

And, how can I create this DLL?



Thanks a lot!

Rui Silva

Do you have the source for this DLL? I think you will find the process
easier if you have this kind of access. Much, Much easier still if the
DLL was originally written in C. If that's the case then everything you
need is in the php source tarball :)

Yep.

There is a great book I can recommend to help you out with this process,
it's called "Advanced PHP Programming" and it is written by George
Schlossnagle (one of the PHP developers). The last two sections of his
book cover extending PHP... and of course the first 20 or so chapters
are pretty useful as well :)

In his example he described writing an extension in C and showed how you
could hook that into PHP as a module. I think that you will be able to
use his example as a skeleton to at least understand how modules are
interpreted by PHP. It's not exactly what you're looking for, but for
cheap advice (the book is less than $50) this is probably as good as
it's going to get :)
