Answer 1

This should work:

$poodle = new poodle();
$class_methods = get_class_methods($poodle);
//echo    $class_methods;
foreach($class_methods as $class_method)
{
    echo $class_method.'\'s Output: '.$poodle->$class_method()."<br />"; 
}

In general:

If you have a value like $test = "abc" you can evaluate it (in php) to either a variablename, or a function etc.:

$test = "abc";
$test() // equal to abc() - if function abc exists.

echo $$test // equal to echo $abc - if $abc is defined.

$anotherTest = new $test(); // equal to new abc() - if class exists.
