accessing a *dll from PHP joomla

I have a *.dll that controls picture file sizes. 开发者_如何转开发It contains a simple function:

CopyPic (PChar: inFileName, outFileName: PChar, MaxSize: Int, MaxWidth: int, MaxHeight: int)

...and returns an int for error checking.

I need to access it from PHP code. I would it run through Java.

I believe you have mixed it all up.

But anyway, take a look at

Check this out. Never used it but other people have reported success...

EDIT You can also probably do it with .NET and/or COM although don't ask me how...
