array_pop($_POST) knocks out all the keys & values in the array..

It's supposed to only boot the last row, what gives?

Is there something I'm doing wrong? The syntax for this function seemed pretty straight forward but it's not working like I was expecting it to. Namely, I just want to remove the last row from the array.
Thx,
Chris

Hi Chris,

I just did a quick test and it worked as expected. Can you post the code excerpt that is not working...?

Heya Dmorison,

Thanks for the quick reply. I was annoyed and already went ahead and wrote a write around for it.

The code I was using was something like:

array_pop($_POST);

$x = 0;
while ($x < sizeof($_POST)):
list($key,$value) = each($_POST);
echo "Key: $key, Value: $value <br />";
$x++;
endwhile;

The output I was getting was:
Key, Value
Key, Value
Key, Value
etc.

When I removed the array_pop line, the while loop displayed all the values correctly. I just needed to dump the submit and hidden values so I didn't bother outputting the popped value into a variable.

I tend to use this

foreach($_POST as $key => $value){
echo "Key: $key, Value: $value <br />";
}

Cool, yes that's much simpler (: Any ideas on why I'm having problems with array_pop?

[jatar_k]

not really but either of the other solutions will work quite well. ;)

Key, Value
should be:
Key: , Value:
u gave the worng test result

correction to script:
reset($_POST);
while (list($key,$value) = each($_POST)) {
echo "Key: $key, Value: $value <br />";
}

Xuefer,

Right, output was as you specified. You're also correct that the array needed to be reset before array_pop would work properly.
Thanks
