I have an array with random number of elements. I analyse each value (by random selection) and unset it after. In one case, If I unset the first element of my array with 2 elements, sort function does not slide value of the second element to the first element. (sorry for my english). 

Exemple :

<?PHP 
  $tb = array (5, 18, 11);
  echo "Values: [0]=$tb[0] [1]=$tb[1] [2]=$tb[2]<BR>";
  unset ($tb[0]);
  echo "After unset: [0]=$tb[0] [1]=$tb[1] [2]=$tb[2]<BR>";
  sort ($tb);
  echo "After sort: [0]=$tb[0] [1]=$tb[1] [2]=$tb[2]<BR>";
  unset ($tb[0]);
  echo "After unset: [0]=$tb[0] [1]=$tb[1]<BR>";
  sort ($tb);
  echo "After sort: [0]=$tb[0] [1]=$tb[1]";
?>

I resolved this trouble by calling implode and explode functions.

bogus,
try using var_dump() on $tb to figure out what happens,
sort() is fine indeed...
