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();
}
?>
