Help sorting array

[benphp]

This is probably simple for someone. I want to sort an array but maintain the array index (0, 1, 2, etc). Here's my example:

 

<?php
$testy = array ();
$testy[] = "zebra";
$testy[] = "alligator";
$testy[] = "panda";
$testy[] = "kangaroo";
asort($testy);
for($K = 0; $K < sizeof($testy); $K++) { 
	$id = $K;
	print "ID = ".$K.";";
	print "Animal = ". $testy[$K];
	print "<br />";
}
?>

 

This sorts the array, but my index gets jacked. It displays:

 

ID = 0;Animal = zebra

ID = 1;Animal = alligator

ID = 2;Animal = panda

ID = 3;Animal = kangaroo

 

I want it to display:

 

ID = 3;Animal = zebra

ID = 0;Animal = alligator

ID = 3;Animal = panda

ID = 2;Animal = kangaroo

 

Help!

edit: Tip for next time. If you know you are close, go to the PHP Doc for that function (in this case sort()), scroll down to See Also, and there is a list of similar functions and what the do. On the doc for sort, asort() is listed in the See Also as

asort() - Sort an array and maintain index association

I've been all through that - usort, sort, asort, - none of them do what I'm trying to do.

The desired data has no correlation to the data you showed us in the example code.

You're right sorry.

 

I want it to display:

 

ID = 1;Animal = alligator

ID = 3;Animal = kangaroo

ID = 2;Animal = panda

ID = 0;Animal = zebra

 

That is, it sorts on the values but retains the indexes.

Your for loop is what is messing things up.  You want the keys to remain in order, but then you access them sequentially.  Doesn't make much sense.

 

 

You could just do a foreach loop:

foreach($testy as $key => $val) {

    //key is the original key

}

That's it. Thanks! What was I thinking.
