I found it impossible to edit values of references like this:
$een = 1;
$twee = 2;
$drie = 3;
$lst = array(&$een, &$twee, &$drie);
foreach ($lst as $c)
$c += 10;
foreach ($lst as $c)
echo("$c \n");
this gives "1 2 3" not "11 12 13" as i would have liked it to
I think this has to do with 'foreach' working on a copy of the array..
Besides "foreach ($lst as &$c)" won't work either.. it isn't accepted by the
php parser. The best solution to handle this array of references is with a while loop.
