大家帮忙优化下吧
getletter方法是把数组的索引转成excel的表头// 数字转字母<br>
function getLetter($num) {<br>
$str = "$num";<br>
$num = intval($num);<br>
if ($num
$ret = chr(ord('A') + intval($str) - 1);<br>
} else {<br>
$first_str = chr(ord('A') + intval(floor($num / 26)) - 1);<br>
$second_str = chr(ord('A') + intval($num % 26) - 1);<br>
if ($num % 26 == 0){<br>
$first_str = chr(ord('A') + intval(floor($num / 26)) - 2);<br>
$second_str = chr(ord('A') + intval($num % 26) + 25);<br>
}<br>
$ret = $first_str.$second_str;<br>
}<br>
return $ret;<br>
}<br>
