Question

I have this problem that I have many huge functions, and I’m using only few in a given script.
Every function sits in its own file. It would be nice to be able to ‘autoload’ or rather require_once a file when given function doesn’t exists.

Maybe is there a way to override Fatal error: Call to undefined function... at the beginning of a script, so everytime that error fires up the script would first try to require_once a file name with name of a non existent function, and then try to call the function again.

Since php 5.3.0 you could do someting like:

class Funcs
{
    public function __callStatic($name, $args) {
        if (!function_exists($name)) {
            require_once sprintf(
                'funcs/%s.func.php', // generate the correct path here
                $name
            );
        }

        if (function_exists($name)) {
            return call_user_func_array($name, $args);
        }
        else {
            // throw some error
        }
    }
}

And then use it like (for example):

Funcs::helloworld();

Which would try to load a file in funcs/helloworld.func.php and execute helloworld after successfull loading.

This way you could ommit the repeated inline tests.
