Thanks for the info.

I have large integer arrays (multi-dimentional) that the DLLs to go through and remove duplicate items in the arrays. I have both a Visual Basic and a C# app that uses the C++ DLLs because putting the code inline with the apps makes the code WAY too slow (part of managed code performance issues). I could easily port the code in the DLLs to PHP if it wouldn't be a performance issue. The DLLs performance with Visual Basic and C# is very good. I just wanted to be able to add some buttons to my website to perform these calculations and output as displayed html files (new tab popup windows).

How would you write and compile a PHP extension that uses the DLL? Does this also depend on what version of PHP the hosting site uses? I'm sort of a PHP newbie, although I'm proficient in other languages. About porting the code to PHP: how would the speed be for intensive mathematical operations? Is PHP designed for this? I guess I could try it to see how it goes.

I have a PHP website with some simple functions. I want to add more functions that use intensive mathematical routines. I want to use a C++ dll to do this. Or I can also compile for *Nix if the necessary for portability. How would I load the .dll (Windows) or .so (*Nix) and then use the functions from it. Any help would be appreciated. Thanks in advance.

I have a Php application that already has 2 buttons with input on the index page that perform some functions and output to different Php pages. Works good. How do I add a button with no input that would just perform a function and then just display a popup window showing the contents of a text file? I want to add several of these buttons for different functions and just display the contents of the resulting text files in popup windows. Any help would be greatly appreciated. Thanks in advance.
