dynamically loadable php files

[kishore.sainath@gmail.com]

I have created a set of classes in PHP for internal use in the company.

Hence I don't explicitly want to "require" or "require_on ce" them
whenever required.

I want to make the library loadable on demand just like mysql or other
libraries in php. I want people to use the classes in my library
without "requiring" anything.

In a nutshell, I want to make my PHP library a .so file in Linux and a
..dll file in Windows.

How do I achieve this?

I currently need a solution for the following combination
Linux, Apache and PHP 5.0.4.

I also welcome a solution on Windows.

Thanks in advance

Hi,

have a look @ the PHP - Manual of new Object model in PHP 5.x
here you could fine the method __autoload() this is exactly what u want :)

Have Fun ..

Re: dynamically loadable php files

I see that __autoload in a global function.

My problem is where do it define the function.

I don't want to do it in the file where use a class.

Define it at the very top of your page. Once it's been defined, you
don't need to define it again. If you're lucky, you have some header
or something that already get's included at the top of every page, so
you could just add it there.

Re: dynamically loadable php files

To avoid all this hassle, is there a way to create a .dll or a .so
file.

A file that I could put in the directory where the mysql and other
libraries reside.
So that I can call them just like any other pre-defined function or
class.

Re: dynamically loadable php files

Sure you can.
You have just to write an PHP - Extension ..
Then you could it use as an PHP Function.

MySQL library usually is NOT loadable "on demand". It is loaded
at the server startup.

Then use the auto_prepend_fi le directive in php.ini. This way,
PHP will parse your file(s) every time it parses anything, and
your classes will be available to any PHP script on your server
without explicitly incluing/requiring them.

You can't. If you want to use the extension mechanism, you have to
write your extension in C.
