    A typical use for this exception, is in conjunction with the is_callable() function.

    For example:

    function foo($arg) {
        $func = 'do' . $arg;
        if (!is_callable($func)) {
            throw new BadFunctionCallException('Function ' . $func . ' is not callable');
        }
    }
