Case-insensitive asort?

[Anon]

I need something that will sort my array values alphabetically and case-insensitively but while maintaining the key index. can anyone help?

[Anon]

natcasesort($array);

natcasesort doesnt keep the key index. I need something that functions exactly like asort but case-insensitively

Sorry to post on such an old thread, but I was looking for the answer to this same question and Google gave me this thread... so I'd like to post the solution I made so that people in the future who Google the question will find it also.

function acasesort($array)
{
//You provide $array, which has Unsorted keys, Unsorted values
$revarr = array_flip($array); //Unsorted values, Unsorted keys
natcasesort($array); //Meaningless keys, Sorted values
$newarr=array();
foreach($array as $value) //Loop through the sorted values
  {
  $newarr[$revarr[$value]] = $value; 
  //The keys of $newarr are the values of $revarr, which are the original keys.
  //The values of $newarr are the original values, sorted with natcasesort.
  }
return $newarr;
}

How it works: The natcasesort splits up the keys and the values, but the foreach puts them back together by looking the values' respective keys in $revarr.

Maybe that's a bad explanation, but I tested the function and it does work, so happy sorting!

Only if your array's values are all distinct strings.

A solution that would have been possible in 2002:

function acasesort($array)
{
    uasort($array, 'strcasecmp');
    return $array;
}
