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...

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) {
