RE: [PHP] removing all duplicate values from an array

Could you >explain how the output would be array('c' => 'zero', 'd' => >'two')?? I was being pretty sloppy with the code (should've posted pseudocode to begin with, my bad) but the general logic is: cycle through each element of the input array. If the value has not been encountered before, store the value and key in a secondary array. If the value has been encountered before (it's present in the secondary array), remove it from the input array, and use the the stored key/value in the secondary array to unset its first instance in the input array, too. --------------------------------------------------------------------- michal migurski- contact info and pgp key: sf/ca http://mike.teczno.com/contact.html
