在YII里面使用PHPExcel external library

首先修改PHPEXCEL /Autoloader.php的文件

public static function Load($pObjectName){     if ((class_exists($pObjectName)) || (strpos($pObjectName, 'PHPExcel') === False)) {        return false;
    }     // this is the code that shows what I am saying     $pObjectFilePath =  PHPEXCEL_ROOT.
       str_replace('_',DIRECTORY_SEPARATOR,$pObjectName).'.php';
 
    if ((file_exists($pObjectFilePath) === false) 
       || (is_readable($pObjectFilePath) === false)) {         return false;
     }      require($pObjectFilePath);
}   // function Load()
 
 
然后
 
 
class TestController extends Controller{  
     // no layouts here      public $layout = '';
 
     public function actionTest()      {      //      // get a reference to the path of PHPExcel classes       $phpExcelPath = Yii::getPathOfAlias('ext.phpexcel.Classes');
 
     // Turn off our amazing library autoload        spl_autoload_unregister(array('YiiBase','autoload'));        
 
     //      // making use of our reference, include the main class      // when we do this, phpExcel has its own autoload registration      // procedure (PHPExcel_Autoloader::Register();)     include($phpExcelPath . DIRECTORY_SEPARATOR . 'PHPExcel.php');
 
     // Create new PHPExcel object      $objPHPExcel = new PHPExcel();
 
     // Set properties      $objPHPExcel->getProperties()->setCreator("Maarten Balliauw")     ->setLastModifiedBy("Maarten Balliauw")     ->setTitle("PDF Test Document")     ->setSubject("PDF Test Document")     ->setDescription("Test document for PDF, generated using PHP classes.")     ->setKeywords("pdf php")     ->setCategory("Test result file");
 
 
     // Add some data      $objPHPExcel->setActiveSheetIndex(0)             ->setCellValue('A1', 'Hello')             ->setCellValue('B2', 'world!')             ->setCellValue('C1', 'Hello')             ->setCellValue('D2', 'world!');
 
      // Miscellaneous glyphs, UTF-8      $objPHPExcel->setActiveSheetIndex(0)             ->setCellValue('A4', 'Miscellaneous glyphs')             ->setCellValue('A5', 'éàèùâêîôûëïüÿäöüç');
 
      // Rename sheet       $objPHPExcel->getActiveSheet()->setTitle('Simple');
 
      // Set active sheet index to the first sheet,        // so Excel opens this as the first sheet      $objPHPExcel->setActiveSheetIndex(0);
 
      // Redirect output to a client’s web browser (Excel2007)       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');
      Yii::app()->end();
 
       // 
       // Once we have finished using the library, give back the         // power to Yii...         spl_autoload_register(array('YiiBase','autoload'));
       } }
