Is there a way to convert a single dimensional array to a multidimensional array where the values of the single dimensional array become the keys to the multidimensional arrays? For example:
$array[1] = 'I';
$array[2] = "want";
$array[3] = "this";
$array[4] = "changed";
would become:
$array['I']['want']['this']['changed'] = '';
BTW, the depth of the resulting multidimensional array is arbitrary.
TIA.
You could use a loop and keep adding a new dimension in each loop....but I Don't understand why you'd want to do anything like this....

Perhaps you could give me an example of "adding a new dimension in each loop".
What I'm trying to do is to create a tree structure. Basically, I have a bunch of topics/sub-topics that are divided by colons. Example:
Political Parties:Republican
Political Parties:Democrat
Conspiracies:Assassinations:JFK
Conspiracies:Assassinations:Martin Luther King, Jr.
Conspiracies:UFOs
What I want is to take these strings and create an array tree, so the result would be:
'Political Parties'
'Republican'
'Democrat'
'Conspiracies'
'Assassinations'
'JFK'
'MLK'
'UFOs'
If you can think of a better way to make this tree from the data above, I'm all for suggestions!
I'm sorry, I was thinking about doing this with references. But after trying 2 methods (a loop and recursion), I found out that string offsets are not compatible with references....so some other way will have to be found...
