PHP import functions

Question

I am trying to find a better pragmatic approach to importing functions on the fly ... let me explain.

Let's say I have a directory with a function name that has the following files:

array_select.func.php
stat_mediam.func.php
stat_mean.func.php
.....

I would like to: upload every single file (which has a function defined internally) and use it just like the php .. internal function, like array_pop (), array_shift (), etc.

As soon as I came across a tutorial (which I can no longer find now) that compiled user-defined functions as part of the PHP installation. Although this is not a good solution, because on the shared / reseller host you cannot recompile the PHP installation.

I do not want to have conflicts with future versions of PHP / other extensions, i.e. if a function called by me X suddenly becomes part of the internal php functions (although it may not have the same functionality as such) I do not want PHP to throw a fatal error because of this and fail.

So the best way I can come up with is to check if a function is defined using function_exists (), if it throws a notification so that it is easily tracked in the log files, otherwise define the function. However, this will probably translate into the fact that I have many include / require statements in other files where I need a function that I don't really like. Or perhaps read the directory and loop over each * .func.php and include_once file. Although I find it a little ugly.

• To automatically upload files as needed, put your functions in classes and use autoload.
• For name conflicts, use namespaces (if you have PHP 5.3).
