大家帮忙看下这段代码哪有问题
<?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 /> echo $str6.'<br/>';<br /> <br /> ?>
