Variable functions

[TheJuice]

Hi,
I know how to use variable variables, and I've been using them for quite some time now.
But here comes a time where I need to use variable functions.

I found a way to do that by using a temporary line like this:
$item_type can be "circuit", "access", etc...,
The function called is get_details_circuit(), get_details_access(), etc...

Here's the code:

$function = 'get_details_'.$item_type;

$details = $function($item_id);

The method above works well, but is there a way to write all of this in just one line?

Yes but:

if ($can_be_optimized) {
optimize( );
}
