Hi,

I was trying to set the same digits that are not side by side, won't be displayed in the output.. how can I edit the script below to accomplish the following ?

For instance for
e.g :
AABC (4 digits number),
it will show only something like 1123, 3122 and not display output like 2129, 1091. Remove those with 2 counts but not side by side.

e.g :
AAAB (3 digits number)
will show 1112, 2333, 7999 from the script below but not 2322, 1121

Please advise. Thank you.

[code:1]
<?php
for($i = 0; $i < 10000; $i++){
$formattedi = str_split(str_pad($i,4,'0',STR_PAD_LEFT));
$count = array_count_values($formattedi);
$min = min($count);
$max = max($count);
if($max == 1) $group = 'all different numbers';
if($max == 2 and $min == 2) $group = 'same numbers in pair';
if ($max == 3) $group = '3 same numbers';
if ($max == 2 and $min ==1) $group = '2 same numbers only';
if($max == 4) $group = '4 same numbers';
$out[$group][] = implode('', $formattedi);
}
echo '<pre>', print_r($out), '</pre>';
?>

Thank you
