Question

Ok I’ve got a unique problem. I have a function being called, and I need this to work with how it’s already being called. I’ve put together some code that shows as close as I can get to the answer:

class some_class {
    private $_some_stuff = array();

    public function some_method()
    {
        $args = func_get_args();
        foreach($args as &$name)
        {
            $this->_some_stuff[] =& $name;
        }
    }

    public function other_method()
    {
        for ($i = 0; $i < count($this->_some_stuff); $i++)
        {
            $this->_some_stuff[$i] = 'somevalue';
        }
    }
}


$some_object = new some_class();
$one = 'firstever';
$two = 'secondever';
$some_object->some_method(&$one, &$two);
$some_object->other_method(&$one, &$two);

echo $one;
echo '<br>...<br>';
echo $two;

I need $one and $two at the end to output ‘somevalue’. If it’s not clear, I need to be able to pass by reference some values into one method of an object and later have a separate method of the object still be able to access those values;

Answer 1

I believe that this works:

public function some_method()
{
    $backtrace = debug_backtrace();
    $args = $backtrace[0]['args'];
    foreach($args as &$name)
    {
        $this->_some_stuff[] =& $name;
    }
}

but as others have said, “how it’s already being called” is call-time pass by reference, which is deprecated
