首先到phpexcel官网上下载最新的phpexcel类,下周解压缩一个classes文件夹,里面包含了PHPExcel.php和PHPExcel的文件夹,这个类文件和文件夹是我们需要的,把classes解压到你项目的一个目录中,重名名为phpexcel,开始喽,(代码都摘自自带实例
 
程序部分
 
require_once \'./phpexcel/PHPExcel.php\';
 
// 首先创建一个新的对象  PHPExcel object
$objPHPExcel = new PHPExcel();
 
// 设置文件的一些属性,在xls文件——>属性——>详细信息里可以看到这些值,xml表格里是没有这些值的
$objPHPExcel
      ->getProperties()  //获得文件属性对象,给下文提供设置资源
      ->setCreator( "Maarten Balliauw")                 //设置文件的创建者
      ->setLastModifiedBy( "Maarten Balliauw")          //设置最后修改者
      ->setTitle( "Office 2007 XLSX Test Document" )    //设置标题
      ->setSubject( "Office 2007 XLSX Test Document" )  //设置主题
      ->setDescription( "Test document for Office 2007 XLSX, generated using PHP classes.") //设置备注
      ->setKeywords( "office 2007 openxml php")        //设置标记
      ->setCategory( "Test result file");                //设置类别
// 位置aaa  *为下文代码位置提供锚
// 给表格添加数据
$objPHPExcel->setActiveSheetIndex(0)             //设置第一个内置表(一个xls文件里可以有多个表)为活动的
            ->setCellValue( \'A1\', \'Hello\'         //给表的单元格设置数据
            ->setCellValue( \'B2\', \'world!\' )      //数据格式可以为字符串
            ->setCellValue( \'C1\', 12)            //数字型
            ->setCellValue( \'D2\', 12)            //
            ->setCellValue( \'D3\', true )           //布尔型
            ->setCellValue( \'D4\', \'=SUM(C1:D2)\' );//公式
 
//得到当前活动的表,注意下文教程中会经常用到$objActSheet
$objActSheet = $objPHPExcel->getActiveSheet();
// 位置bbb  *为下文代码位置提供锚
// 给当前活动的表设置名称
$objActSheet->setTitle(\'Simple2222\');
代码还没有结束,可以复制下面的代码来决定我们将要做什么
 
我们将要做的是
1,直接生成一个文件
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, \'Excel2007\');
$objWriter->save(\'myexchel.xlsx\');
 
2、提示下载文件
excel 2003 .xls
// 生成2003excel格式的xls文件
header(\'Content-Type: application/vnd.ms-excel\');
header(\'Content-Disposition: attachment;filename="01simple.xls"\');
header(\'Cache-Control: max-age=0\');
 
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, \'Excel5\');
$objWriter->save(\'php://output\');
exit;
 
excel 2007 .xlsx
// 生成2007excel格式的xlsx文件
header(\'Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet\');
header(\'Content-Disposition: attachment;filename="01simple.xlsx"\');
header(\'Cache-Control: max-age=0\');

$objWriter = PHPExcel_IOFactory:: createWriter($objPHPExcel, \'Excel2007\');
$objWriter->save( \'php://output\');
exit;

pdf 文件
// 下载一个pdf文件
header(\'Content-Type: application/pdf\');
header(\'Content-Disposition: attachment;filename="01simple.pdf"\');
header(\'Cache-Control: max-age=0\');

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, \'PDF\');
$objWriter->save(\'php://output\');
exit;
// 生成一个pdf文件
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, \'PDF\');
$objWriter->save(\'a.pdf\');


CSV 文件
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, \'CSV\')->setDelimiter(\',\' )  //设置分隔符
                                                                  ->setEnclosure(\'"\' )    //设置包围符
                                                                  ->setLineEnding("\r\n" )//设置行分隔符
                                                                  ->setSheetIndex(0)      //设置活动表
                                                                  ->save(str_replace(\'.php\' , \'.csv\' , __FILE__));

HTML 文件
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, \'HTML\');       //将$objPHPEcel对象转换成html格式的
$objWriter->setSheetIndex(0);  //设置活动表
//$objWriter->setImagesRoot(\'http://www.example.com\');

导入或读取文件
//通过PHPExcel_IOFactory::load方法来载入一个文件,load会自动判断文件的后缀名来导入相应的处理类,读取格式保含xlsx/xls/xlsm/ods/slk/csv/xml/gnumeric
require_once \'../Classes/PHPExcel/IOFactory.php\';
$objPHPExcel = PHPExcel_IOFactory::load(
//吧载入的文件默认表(一般都是第一个)通过toArray方法来返回一个多维数组
$dataArray = $objPHPExcel->getActiveSheet()->toArray();
//读完直接写到一个xlsx文件里
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, \'Excel2007\'); //$objPHPExcel是上文中读的资源
$objWriter->save(str_replace(\'.php\', \'.xlsx\', __FILE__));

读取xml文件
$objReader = PHPExcel_IOFactory:: createReader(\'Excel2003XML\' );
$objPHPExcel = $objReader->load( "Excel2003XMLTest.xml" );
读取ods文件
$objReader = PHPExcel_IOFactory:: createReader(\'OOCalc\' );
$objPHPExcel = $objReader->load("OOCalcTest.ods" );
读取numeric文件
$objReader = PHPExcel_IOFactory:: createReader(\'Gnumeric\' );
$objPHPExcel = $objReader->load( "GnumericTest.gnumeric" );
读取slk文件
$objPHPExcel = PHPExcel_IOFactory:: load("SylkTest.slk" );
 
 
循环遍历数据
$objReader = PHPExcel_IOFactory::createReader(\'Excel2007\' ); //创建一个2007的读取对象
$objPHPExcel = $objReader->load ("05featuredemo.xlsx" );             //读取一个xlsx文件
foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) {     //遍历工作表
       echo \'Worksheet - \' , $worksheet->getTitle() , PHP_EOL;
       foreach ($worksheet->getRowIterator() as $row) {       //遍历行
             echo \'    Row number - \' , $row->getRowIndex() , PHP_EOL;
            $cellIterator = $row->getCellIterator();   //得到所有列
            $cellIterator->setIterateOnlyExistingCells( false); // Loop all cells, even if it is not set
             foreach ($cellIterator as $cell) {  //遍历列
                   if (!is_null($cell)) {  //如果列不给空就得到它的坐标和计算的值
                         echo \'        Cell - \' , $cell->getCoordinate() , \' - \' , $cell->getCalculatedValue() , PHP_EOL;
                  }
            }
      }
}

吧数组插入的表中
//插入的数据 3行数据
$data = array( array(\'title\'      => \'Excel for dummies\',
                     \'price\'      => 17.99,
                     \'quantity\'   => 2
                           ),
                    array(\'title\'       => \'PHP for dummies\',
                           \'price\'      => 15.99,
                           \'quantity\'  => 1
                           ),
                    array(\'title\'      => \'Inside OOP\',
                           \'price\'      => 12.95,
                           \'quantity\'  => 1
                           )
                   );
$baseRow = 5;      //指定插入到第5行后
foreach($data as $r => $dataRow) {
      $row = $baseRow + $r;    //$row是循环操作行的行号
      $objPHPExcel->getActiveSheet()->insertNewRowBefore($row,1);  //在操作行的号前加一空行,这空行的行号就变成了当前的行号
       //对应的咧都附上数据和编号
      $objPHPExcel->getActiveSheet()->setCellValue( \'A\'.$row, $r+1);     
      $objPHPExcel->getActiveSheet()->setCellValue( \'B\'.$row, $dataRow[\'title\']);
      $objPHPExcel->getActiveSheet()->setCellValue( \'C\'.$row, $dataRow[\'price\']);
      $objPHPExcel->getActiveSheet()->setCellValue( \'D\'.$row, $dataRow[\'quantity\']);
      $objPHPExcel->getActiveSheet()->setCellValue( \'E\'.$row, \'=C\'.$row.\'*D\' .$row);
}
$objPHPExcel->getActiveSheet()->removeRow($baseRow-1,1);     //最后删去第4行,这是示例需要,在此处为大家提供删除实例
