Not a bug. The unset ($ar) in the unset all function removes the
reference to the global variabele.
Use unset($GLOBALS["ar"]) if you want this to work.

unset in function doesn't work on global arrays

example:

<?php
{
  function ListIt() {
    global $ar;
    if (is_array($ar)) {
      foreach($ar as $k => $v) {
        echo "ar[$k] = $v <br>\n";
      }
    } else {
      echo "empty/nonarray <br>\n";
    }
    echo "<br>\n";
  }

  function UnsetOne($i) {
    global $ar;
    unset($ar[$i]);
  }

  function UnsetAll() {
    global $ar;
    //echo "t1s: <br>\n"; ListIt(); echo ":t1e <br>\n";
    unset($ar);
    //echo "t2s: <br>\n"; ListIt(); echo ":t2e <br>\n";
  }

  echo "init: <br>\n";
  $ar = array();
  $ar[1] = "a";
  $ar[2] = "b";
  $ar[3] = "c";
  $ar[4] = "d";
  ListIt();

  echo "unset 3: <br>\n";
  UnsetOne(3);
  ListIt();

  echo "unset all (global array in function): <br>\n";
  UnsetAll();
  ListIt();

  echo "unset all (top level): <br>\n";
  unset($ar);
  ListIt();

}
?>
