phpexcel如何读和写大于26列的excel

主要运用到PHPExcel_Cell类的两个方法

1读取excel大于26列时.

PHPExcel_Cell::columnIndexFromString($highestColumm)://由列名转化为列索引数字 'A->0,Z->25'

1>计算出总列数

$highestColumm = $sheet->getHighestColumn(); // 获得最多的列数,返回列名的大写字母  如 'AB','F'等

2>计算出列对应的索引

$end_index     = PHPExcel_Cell::columnIndexFromString($highestColumm);//由列名转为列数('AB'->28)

$PHPExcel      = $reader->load($file_path_root . '/' . $file_name);//文件路径加载文件名
        $sheet         = $PHPExcel->getSheet(0);
        $highestRow    = $sheet->getHighestRow(); // 取得总行数
        $highestColumm = $sheet->getHighestColumn(); // 取得总列数
        $end_index     = PHPExcel_Cell::columnIndexFromString($highestColumm);//由列名转为列数('AB'->28)

        $titles  = array();
        $content = array();
        /** 循环读取每个单元格的数据 */
        for ($row = 1; $row <= $highestRow; $row++) {
            for ($column = 0; $column < $end_index; $column++) {
                $col_name = PHPExcel_Cell::stringFromColumnIndex($column);//由列数反转列名(0->'A')
                $value    = mb_convert_encoding($sheet->getCell($col_name . $row)->getValue(), 'gbk', 'utf8');//转码
                if ($row == 1) {
                    //获取表头
                    $titles[] = preg_replace('/\s/', '', $value);
                } else {
                    if ($sheet->getCell($col_name . $row)->getDataType() == PHPExcel_Cell_DataType::TYPE_NUMERIC) {
                        //数字类型时,三位精度标准来比较该数是否在0,1之间,转换为百分数,保留一位小数
                        if (bccomp(floatval($value), floatval('1'), 3) == -1 && bccomp(floatval($value), floatval('0'), 3) == 1) {
                            $value = sprintf("%01.1f", $value * 100) . '%';
                        }
                    }
                    $content[$row][$column] = preg_replace('/\s/', '', $value);
                }
            }
        }

ps:

 

上传excel时,如果没有读写权限,可以写到tmp目录下,这个目录下一般都是有读写权限的.

2写大于26列的excel

$title_col = PHPExcel_Cell::stringFromColumnIndex($k);//标题行列名,由列索引反转列名(0->'A')

</pre><pre name="code" class="php"><pre name="code" class="php">foreach($titles as $k =>$t)
{
       $title_col = PHPExcel_Cell::stringFromColumnIndex($k);//标题行列名,由列索引反转列名(0->'A')
       $this->_objPHPExcel->getActiveSheet()->getColumnDimension($title_col)->setWidth(12);
       $this->_objPHPExcel->setActiveSheetIndex()->getStyle($title_col."1")->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
       $this->_objPHPExcel->getActiveSheet()->setCellValue($title_col."1",iconv('GBK','UTF-8//IGNORE',$t));//标题行
}

3读取excel百分号时自动转化为了小数

处理单元格数据时,如果有百分号小数会自动转为小数,处理时需要判断单元格数据类型,因为初步认定只有百分数是小数,其余各列不存在小数.故处理结果:

判断数据类型为数字,其余几种类型都在 PHPExcel_Cell_DataType类中:

 

/* Data types */
    const TYPE_STRING2  = 'str';
    const TYPE_STRING   = 's';
    const TYPE_FORMULA  = 'f';
    const TYPE_NUMERIC  = 'n';
    const TYPE_BOOL     = 'b';
    const TYPE_NULL     = 'null';
    const TYPE_INLINE   = 'inlineStr';
    const TYPE_ERROR    = 'e';

if ($sheet->getCell($col_name . $row)->getDataType() == PHPExcel_Cell_DataType::TYPE_NUMERIC) {
                        //数字类型时,三位精度标准来比较该数是否在0,1之间,转换为百分数,保留一位小数
                        if (bccomp(floatval($value), floatval('1'), 3) == -1 && bccomp(floatval($value), floatval('0'), 3) == 1) {
                            $value = sprintf("%01.1f", $value * 100) . '%';
                        }
}

判断浮点数是否在0-1之间(三位精度),然后组合成百分数即可:

$value = sprintf("%01.1f", $value * 100) . '%';
