PHP读取excel

 使用PHPExcel来读取excel文件，以下代码读取出来的文件包含标题栏

注：单元格第一行以1开始，第一列以0开始

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

class ExcelHelper{
	public function importFileContacts($filename){
		try {
                        //解决文件中文名问题
			$filename = iconv("UTF-8","GB2312",$filename);
            if (!file_exists($filename)) {
                return false;
            }
            //chmod($filename, 0750);linux下改变文件权限
            $filetype = $this->getFileType($filename);
            //根据文件类型读取excel文件
            if ($filetype == "xlsx") {
                $objReader = PHPExcel_IOFactory::createReader('Excel2007');
                $objReader->setReadDataOnly(true);

            $highestColumn = $objWorksheet->getHighestColumn(); // e.g 'F'
            $highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn); // e.g. 5
