public static function stringFromColumnIndex($pColumnIndex = 0) { // Using a lookup cache adds a slight memory overhead, but boosts speed // caching using a static within the method is faster than a class static, // though it's additional memory overhead static $_indexCache = array(); if (!isset($_indexCache[$pColumnIndex])) { // Determine column string if ($pColumnIndex < 26) { $_indexCache[$pColumnIndex] = chr(65 + $pColumnIndex); } elseif ($pColumnIndex < 702) { $_indexCache[$pColumnIndex] = chr(64 + ($pColumnIndex / 26)) . chr(65 + $pColumnIndex % 26); } else { $_indexCache[$pColumnIndex] = chr(64 + (($pColumnIndex - 26) / 676)) . chr(65 + ((($pColumnIndex - 26) % 676) / 26)) . chr(65 + $pColumnIndex % 26); } } return $_indexCache[$pColumnIndex]; }
PHPExcel_Cell::stringFromColumnIndex($i); // 从o开始
将列的字母转成数字序号使用,代码如下:
PHPExcel_Cell::columnIndexFromString('AA');
