<?php<br />
$str='abcdefghijklmnopqrstuvwxyz'; <br />
$count = 123456789;<br />
<br />
$str1 = $str[floor(floor(floor(floor(floor($count/26)/26)/26)/26)/26)];<br />
$str2 = $str[floor(floor(floor(floor($count/26)/26)/26)/26)%26];<br />
$str3 = $str[floor(floor(floor($count/26)/26)/26)%26];<br />
$str4 = $str[floor(floor($count/26)/26)%26];<br />
$str5 = $str[floor($count/26)%26];<br />
$str6 = $str[$count%26];<br />
echo $str1.'<br/>';<br />
echo $str2.'<br/>';<br />
echo $str3.'<br/>';<br />
echo $str4.'<br/>';<br />
echo $str5.'<br/>';<br />
