Question

I have the following array, which I would like to reindex so the keys are reversed (ideally starting at 1):

Current array (edit: the array actually looks like this):

Array (  [2] => Object     (         [title] => Section         [linked] => 1     )  [1] => Object     (         [title] => Sub-Section         [linked] => 1     )  [0] => Object     (         [title] => Sub-Sub-Section         [linked] =>      )  ) 

How it should be:

Array (  [1] => Object     (         [title] => Section         [linked] => 1     )  [2] => Object     (         [title] => Sub-Section         [linked] => 1     )  [3] => Object     (         [title] => Sub-Sub-Section         [linked] =>      )  ) 

Answer 1

If you want to re-index starting to zero, simply do the following:

$iZero = array_values($arr); 

If you need it to start at one, then use the following:

$iOne = array_combine(range(1, count($arr)), array_values($arr)); 

Here are the manual pages for the functions used:

• array_values()
• array_combine()
• range()
