Description:
------------
SPL interfaces provide useful interfaces to let objects behave like arrays; however, there is no way for objects to use the array append syntax method without having to extend either ArrayObject or ArrayIterator. I am suggesting that a new interface called Appendable be created to allow objects to have this functionality without having to be an extension of anything.

Appendable would only contain a single method, but would almost always be used with ArrayAccess, Appendable differs from the feature request (#32347) I posted earlier since it is not an extension of ArrayAccess.

This is unnecessary.  the offset is set to null when [] is requested

<?php
class test implements ArrayAccess
{
    var $test = array();
    function offsetGet($var)
    {
        return $this->test[$var];
    }
    function offsetSet($var, $value)
    {
        if ($var === null) {
            $this->test[] = $value;
        }
        $this->test[$var] = $value;
    }
    function offsetExists($var)
    {
        return isset($this->test[$var]);
    }
    function offsetUnset($var)
    {
        unset($this->test[$var]);
    }
}

$a = new test;
$a[] = 1;
echo $a[0];
?>
