sortign string - why this difference?

[Sonnich]

Hi!

I have 2 arrays which I sort ny the first one.

for($i=0;$i<(count($item1)-1);$i++)
{
$k = $i;
for($j=$i;$j<(count($item1)-1);$j++);
{
if (strcmp($item1[$k],$item1[$j])<0)
$k = $j;
}
if($k<>$i)
{
$temp=$item1[$i]; $item1[$i]=$item1[$k];
$item1[$k]=$temp;
$temp=$item2[$i]; $item2[$i]=$item2[$k];
$item2[$k]=$temp;
}
}

Pretty simple - it works, I get the highest item first - I'd like it
the other way.

But
if (strcmp($item1[$j],$item1[$k])<0) // k an j switched
does not work, though
if (strcmp($item1[$j],$item1[$k])>0) // < replaced by >
does work, but it is descending

why this?

I can read my array backwards, it is ok, but why this????

BB345324
BB235342
XX3634543
T44444 <- this is rare, but might happen
TR000001

Sonnich,

Most likelly your an error here:
for($j=$i;$j<(count($item1)-1);$j++);
This "for" is an empty "for" that just does nothing, because its body
is empty--it is closed by the the last ";" in the line.
