PHPExcel是一个非常方便生成Excel格式文件的类,官方下载包中带有大量如何生成各种样式excel文件的示例,但没有一个读取Excel文件的完整例子.Xiaoqiang根据网上的资料,整理了一份简单读取Excel文件的例子

<script>ec(2);</script>

在网站的管理后台经常会使用到报表的生成和读取,CSV和Excel都是常用的报表格式,CSV相对来说比较简单,如果大家有疑问我会相继发布一些CSV的实例,这里主要介绍用PHP 来生成和读取Excel文件。

要执行下面的函数,首先要引入一个类库:PHPExcel,PHPExcel是一个强大的PHP类库,用来读写不同的文件格式,比如说Excel 2007,PDF格式,HTML格式等等,这个类库是建立在Microsoft's OpenXML和PHP 的基础上的,对Excel提供的强大的支持,比如设置工作薄,字体样式,图片以及边框等等,下面来看看它是如何读写Excel文件的:

首先来看如果生成Excel文件:
下面这代码中函数arrayToExcel的功能是把一个二维数组的数据生成一个excel文件,并且保存在服务器上。

 代码如下 复制代码
require_once 'Classes/PHPExcel/Reader/Excel2007.php';
require_once 'Classes/PHPExcel/Reader/Excel5.php';
include 'Classes/PHPExcel/IOFactory.php';
function arrayToExcel($data){
$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setTitle('firstsheet');
$objPHPExcel->getDefaultStyle()->getFont()->setName('Arial');
$objPHPExcel->getDefaultStyle()->getFont()->setSize(10);
//add data
$i = 2;
foreach ($data as $line){
$objPHPExcel->getActiveSheet()->setCellValue('A'.$i, $line['From']);
$objPHPExcel->getActiveSheet()->getCell('A'.$i)->setDataType('n');
$objPHPExcel->getActiveSheet()->setCellValue('B'.$i, $line['To']);
$objPHPExcel->getActiveSheet()->getCell('B'.$i)->setDataType('n');
$i++;
}
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$file = 'excel.xls';
$objWriter->save($file);
}

如果你不希望保存在服务器上,希望生成以后直接下载到客户端,可以在输出文件的时候加入下面的代码,而不使用 $objWriter->save($file);

 代码如下 复制代码

header("Pragma: public");
header("Expires: 0");
header("Cache-Control:must-revalidate, post-check=0, pre-check=0");
header("Content-Type:application/force-download");
header("Content-Type:application/vnd.ms-execl");
header("Content-Type:application/octet-stream");
header("Content-Type:application/download");
header('Content-Disposition:attachment;filename="excel.xls"');
header("Content-Transfer-Encoding:binary");
$objWriter->save('php://output');

接下来看一个读取Excel文件内容的实例:
下面这代码中函数excelToArray的功能是把一个excel里的内容重新整理放到一个数组了。

 代码如下 复制代码
require_once 'Classes/PHPExcel.php';
require_once 'Classes/PHPExcel/IOFactory.php';
function excelToArray($file){
$objReader = PHPExcel_IOFactory::createReader('Excel5');
$objReader->setReadDataOnly(true);
$objPHPExcel = $objReader->load($file);
$objWorksheet = $objPHPExcel->getActiveSheet();
$highestRow = $objWorksheet->getHighestRow();
$highestColumn = $objWorksheet->getHighestColumn();
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
$excelData = array();
for ($row = 2; $row for ($col = 0; $col getCellByColumnAndRow($col, $row)->getValue();
}
}
return $excelData;
}


精简办法

 

 代码如下 复制代码
/**

 * @author Xiaoqiang.Wu
 * @version 1.01
 */
 
error_reporting(E_ALL);

/** PHPExcel_IOFactory */
require_once '../Classes/PHPExcel/IOFactory.php';
 
 
// Check prerequisites
if (!file_exists("31excel5.xls")) {
    exit("not found 31excel5.xls.n");
}
 
$reader = PHPExcel_IOFactory::createReader('Excel5'); //设置以Excel5格式(Excel97-2003工作簿)
$PHPExcel = $reader->load("31excel5.xls"); // 载入excel文件
$sheet = $PHPExcel->getSheet(0); // 读取第一??工作表
$highestRow = $sheet->getHighestRow(); // 取得总行数
$highestColumm = $sheet->getHighestColumn(); // 取得总列数
 
/** 循环读取每个单元格的数据 */
for ($row = 1; $row     for ($column = 'A'; $column         $dataset[] = $sheet->getCell($column.$row)->getValue();
        echo $column.$row.":".$sheet->getCell($column.$row)->getValue()."
";
    }
}
