what if you have three headers depending on what colors a user likes. this favorite color is stored
in a session variable
$fav_color = 'blue_header';
<?php
function blue_header()
{
}
function red_header()
{
}
function green_header()
{
}
include_once('session.egn');
call_user_func($fav_color);
?>
there are obviously easier ways todo this, but its a simple example.

I took a look at this page (and all the functions referenced
therein). While there must be a use for these functions
otherwise they wouldn't have been included in PHP, I'm at
a total loss as to why anyone would ever use them. Why
wouldn't you just call the function (or do whatever) yourself?
Could anyone offer some insight?
