Re: [PHP] array_unique() workaround? SOLUTION!
Thanks everyone for the ideas,
Here's what I came up with...
I forgot to mention that I needed to preserve the original array's keys.
Here is a replacement I wrote that seems to work. Let me know if you see
errors in it or have improvements.
function my_array_unique($somearray)
{
asort($somearray);
reset($somearray);
$currentarrayvar = current($somearray);
foreach ($somearray as $key=>$var)
{
if (next($somearray) != $currentarrayvar)
{
$uniquearray[$key] = $currentarrayvar;
$currentarrayvar = current($somearray);
}
}
reset($uniquearray);
return $uniquearray;
}

Re: [PHP] array_unique() workaround? SOLUTION!
it seems that...
$newarray = array()
foreach($oldarray as $key => $value)
if(! isset($newarray[$key]))
$newarray[$key] = $value;

reset() is not needed when using foreach but is requirement when using :
each(),next(),prev(), etc.
