You could always use a for loop enbeded in a while loop to walk through a
linked list.
<html>
<body>
<?php
$Arr1[1] = "Apple";
$Arr1[2] = "Banana";
$Arr1[3] = &$Arr2;
$Arr2[1] = "Carrot";
$Arr2[2] = &$Arr3;
$Arr3[1] = "Orange";
$Arr3[2] = "Peach";
$Arr3[3] = ""; //Anything that is used to define the end of the list.
print_r($Arr1); //used a pre-existing function.
$handle = &$Arr1;
while ($handle != ""){
for( $i=1; $i < sizeof($handle) ; $i++){
echo " ";
echo $handle[$i];
}
$handle = $handle[sizeof($handle)]; //last value in the array contains the
address of the next array.
}
?>
</body>
</html>
You could expand the list out as long as you have memory and this function
would walk through it until it found the end. But the true questions is why
would you want to when you can already dynamically change the size of arrays
in php.

Easier yes and ok for debug but it doesnt look very nice on a web page does
it nor does it help if you want to do something with the array elements.
