I do something like that, too. My way might be even more
clunky.

<?php

function sum() {
    $args = func_get_args();
    if (!count($args)) {
        echo 'You have to supply something to the
function.';
    } elseif (count($args) == 1) {
        return $args[0];
    } elseif (count($args) == 2) {
        if (is_numeric($args[0]) &&
is_numeric($args[1])) {
            return $args[0] + $args[1];
        } else {
            return $args[0] . $args[1];
        }
    }
}

?>

I like the "__call" method, though. You can
"declare" multiple functions that don't pollute
the namespace. Although, it might be better looking to use
this instead of a series of if...elseif... statemenets.

<?php
class myClass {
    function __call($fName, $fArgs) {
        switch($fName) {
            case 'sum':
            if (count ($fArgs) === 1) {
                return $fArgs[0];
            } else {
                $retVal = 0;
                foreach( $fArgs as $arg ) {
                    $retVal += $arg;
                }
                return $retVal;
            }
            break;
            case 'other_method':
            ...
            default:
            die ('<div><b>Fetal Error:</b>
unknown method ' . $fName . ' in ' . __CLASS__ .
'.</div>');
        } // end switch
    }
}

?>

Side note: if you don't force lower/upper case, you will
have case sensitive method names. E.g. $myclass->sum()
!== $myclass->Sum().
