associal array problem

[quicknik]

hi folks,

i discovered the following miracle:

lst["master"][$newentry]=array('','');

works as long as $newentry is a string.
when $newentry is a number like 123
it produces the following (dumpvar)
[0]=>
array(2) {
[0]=>
string(0) ""
[1]=>
string(0) ""

i already tried :
lst["master"][(string)$newentry]=array'','');

and
lst["master"][sprintf($newentry)]=array('','');

because i thought it could be a problem of typjuggling. But it didn't help.
Any ideas ?
bye,
Niko

forget the above i figured it out by
myself:

the problem was that i was doing an
array_merge later in the script
which cause this effekt
