THis is expected behavior,
if current($pole) evaluates to 0, it's considered false as a while conditition:
while (current($pole)) { --- while (0) {
You want to use:
while (current($pole) !== FALSE) {

Associative arrays seems to be broken in some way.
it is impossible to use something like
$variable[something]=0;
example scripts:
A:
?
$userdata[user_star]='10';
$userdata[user_pohlavi]=U;
$userdata[user_count]=1;
$userdata[user_vip]=N;
$userdata[user_lang]=CZ;
$userdata[user_tld]=CZ;
$userdata[user_fags]=A;
show_values($userdata);
function show_values($pole)
{
echo show;
reset($pole);
while(current($pole))
{
echo index: .key($pole). value: .current($pole).br;
next($pole);
}
}
?
Following script show proper results:
showindex: user_star value: 10
index: user_pohlavi value: U
index: user_count value: 1
index: user_vip value: N
index: user_lang value: CZ
index: user_tld value: CZ
index: user_fags value: A
But
Script B:
?
$userdata[user_star]='10';
$userdata[user_pohlavi]=U;
$userdata[user_count]=0;
$userdata[user_vip]=N;
$userdata[user_lang]=CZ;
$userdata[user_tld]=CZ;
$userdata[user_fags]=A;
show_values($userdata);
function show_values($pole)
{
echo show;
reset($pole);
while(current($pole))
{
echo index: .key($pole). value: .current($pole).br;
next($pole);
}
}
?
(only thig I change is : $userdata[user_count]=0; )
give INCORRECT result
showindex: user_star value: 10
index: user_pohlavi value: U
..and rest of the array gone.
PHP manual say that A 'key' is either a nonnegative integer or a string... ..A
'value' can be anything. , so I thing I found bug...

or even better: use each() or foreach()
