require(ROOT_PATH . 'includes/PHPExcel.php');//引入PHP EXCEL类
function format_excel2array($filePath='',$sheet=){

        $PHPReader = new PHPExcel_Reader_Excel2007();        //建立reader对象
        if(!$PHPReader->canRead($filePath)){
                $PHPReader = new PHPExcel_Reader_Excel5();
                if(!$PHPReader->canRead($filePath)){
                        echo 'no Excel';

        }
        $PHPExcel = $PHPReader->load($filePath);        //建立excel对象
        $currentSheet = $PHPExcel->getSheet($sheet);        //**读取excel文件中的指定工作表*/
        $allColumn = $currentSheet->getHighestColumn();        //**取得最大的列号*/
        $allRow = $currentSheet->getHighestRow();        //**取得一共有多少行*/
        $data = array();
        for($rowIndex=;$rowIndex<=$allRow;$rowIndex++){        //循环读取每个单元格的内容。注意行从1开始，列从A开始
                for($colIndex='A';$colIndex<=$allColumn;$colIndex++){
                        $addr = $colIndex.$rowIndex;
                        $cell = $currentSheet->getCell($addr)->getValue();
                        if($cell instanceof PHPExcel_RichText){ //富文本转换字符串
                                $cell = $cell->__toString();
                        }
                        $data[$rowIndex][$colIndex] = $cell;
                }
        }
        return $data;
}

使用方法：
                        $filePath = ROOT_PATH.'data/diamondStock.xlsx';        //钻石库存文件
                        $data = format_excel2array($filePath);
                        print_r($data);die;
