yii中 集成PHPExcel 实现excel导入

1. 下载PHPexcel    http://phpexcel.codeplex.com/releases/view/96183
2. 下载完成后将其解压至extensions/yiiexcel下 yiiexcel是后来创建的文件夹
3. 修改PHPExcel/Autoloader.php文件 将PHPExcel/Autoloader.php文件修改为

   		$pClassFilePath = PHPEXCEL_ROOT .
   						  str_replace('_',DIRECTORY_SEPARATOR,$pClassName) .
   						  '.php';

   			//	Can't load
   			return FALSE;
   		}
   
   		require($pClassFilePath);
   	}	//	function Load()
   
   }

4. 在控制器的方法中写入代码

		Yii::import('ext.yiiexcel.PHPExcel',true);
		Yii::import('ext.yiiexcel.PHPExcel.IOFactory',true);
		Yii::import('ext.yiiexcel.PHPExcel.Reader.Excel5',true);
		$objReader = PHPExcel_IOFactory::createReader('Excel5');//use excel2007 for 2007 format 
		
		$objPHPExcel = $objReader->load('sensitive.xls'); //$filename可以是上传的文件，或者是指定的文件
		$sheet = $objPHPExcel->getSheet(0); 
		$highestRow = $sheet->getHighestRow(); // 取得总行数 
		$highestColumn = $sheet->getHighestColumn(); // 取得总列数



		//循环读取excel文件,读取一条,插入一条
		//j表示从哪一行开始读取
		
	
		for($j=2;$j<=$highestRow;$j++)
		{
			$a = $objPHPExcel->getActiveSheet()->getCell("A".$j)->getValue();//获取A列的值
			$b = $objPHPExcel->getActiveSheet()->getCell("B".$j)->getValue();//获取B列的值
			$c = $objPHPExcel->getActiveSheet()->getCell("C".$j)->getValue();//获取C列的值
			echo $a.'---'.$b.'---'.$c.'<br />';
		}
