The second array also contains pointers to 'subtrees' of the first array. Anyway, I discovered a strange behavior when I dumped the tree before and after making the pointers.
Example:
<?php $tree = array( 1 => array( 2 => 'foo' ) );
var_dump($tree);
$b = &$tree[1];
var_dump($tree); ?>
This code will output the following:
array(1) {
[1]=>
array(1) {
[2]=>
string(3) "foo"
}
}
array(1) {
[1]=>
&array(1) {
[2]=>
string(3) "foo"
}
}As you can see the original tree now contains a pointer, how can that be, I didn't change the original array!?
So what I'd like to know is: Is this intended behavior, and if so: why does it work like this and would it make some operations impossible?
