Hi;

How could i get rid off the repeat words from an array? Thanks

eg;

$a[]="the , think , this , that , the , their , that , the , the , those";

i just want the array reduce to "the, think, that,those".

foreach ($a as &$wordlist):
  $temp = explode(',', $wordlist);
  $temp = array_map('trim', $temp);
  $temp = array_unique($temp, SORT_STRING);
  $wordlist = $temp;
endforeach;
