我想用 PHPExcel 从 Excel 工作表中删除所有以“//”开头的行。我的代码：

require '../Classes/PHPExcel.php';
require_once '../Classes/PHPExcel/IOFactory.php';

error_reporting(E_ALL & ~E_STRICT & ~E_NOTICE);


$path = "del_head.xls";

$objPHPExcel = PHPExcel_IOFactory::load($path);
$objWorksheet = $objPHPExcel->getActiveSheet();
$highestRow = $objWorksheet->getHighestRow();
$highestColumn = $objWorksheet->getHighestColumn();
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);


for($row=1; $row < $highestRow; ++$row){
   $value = $objPHPExcel->getActiveSheet()->getCell('A'.$row)->getValue();

   if (substr($value,0,2) == "//") {
      $objPHPExcel->getActiveSheet()->removeRow($row, $row);
      }
}

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, "Excel2007");
$objWriter->save($path);

但是，代码不会删除所有以“//”开头的行。我认为问题出在函数“removeRow”上。

非常感谢您提前。
