利用PHPExcel实现数据保存到excel文件

    include(dirname(__FILE__) .'/phpexcel-1.7.7/Classes/PHPExcel.php');
    include(dirname(__FILE__) .'/phpexcel-1.7.7/Classes/PHPExcel/IOFactory.php');


    $header_arr = array('A','B','C','D','E','F','G','H','I','J','K','L','M', 'N','O','P','Q','R','S','T','U','V','W','X','Y','Z');
    $objPHPExcel = new PHPExcel();//实例化一个要保存的phpExcel对象

//写数据开始

    //在激活的工作区写入数据 (单条写入数据演示)
    $objPHPExcel->getActiveSheet()->setCellValue('B8', '汉字');

    //在激活的工作区写入数据 (数组写入数据演示)
    $startRow = 1;
    foreach ($list as $row) {
        foreach ($indexKey as $key => $value){
            //这里是设置单元格的内容
            $objActSheet->setCellValue($header_arr[$key].$startRow,$row[$value]);
        }
        $startRow++;
    }


//写数据结束

    $objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);
    $objWriter->save($file);

php excel 设置单元格格式为文本格式

1、设置单元格为文本

//设置A3单元格为文本
$objPHPExcel->getActiveSheet()->getStyle('A3')->getNumberFormat()
    ->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_TEXT);
//也可以设置整行或整列的style
/*
//E 列为文本
$objPHPExcel->getActiveSheet()->getStyle('E')->getNumberFormat()
    ->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_TEXT);
//第三行为文本
$objPHPExcel->getActiveSheet()->getStyle('3')->getNumberFormat()
    ->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_TEXT);
*/

2、在设置值的时候显示的指定数据类型

$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setTitle('Simple');

$objPHPExcel->getActiveSheet()->setCellValueExplicit('D1',123456789033,PHPExcel_Cell_DataType::TYPE_STRING);

3、在数字字符串前加一个空格使之成为字符串

$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setTitle('Simple');

$objPHPExcel->getActiveSheet()->setCellValue('D1', ' ' . 123456789033);

单元格宽度设置和自适应

//设置宽度      
$objPHPExcel->$objActSheet->getColumnDimension('B')->setAutoSize(true);      
$objPHPExcel->$objActSheet->getColumnDimension('A')->setWidth(30);

 设置默认高度

//设置默认行高
$objPHPExcel->getActiveSheet()->getDefaultRowDimension()->setRowHeight(30);
