超实用的PHPExcel[导入][导出]实现方法总结

首先需要去官网https://github.com/PHPOffice/PHPExcel/下载PHPExcel，下载后只需要Classes目录下的文件即可。

1、PHPExcel导出方法实现过程

/**
 * 数据导出
 * @param array $title   标题行名称
 * @param array $data   导出数据
 * @param string $fileName 文件名
 * @param string $savePath 保存路径
 * @param $type   是否下载  false--保存   true--下载
 * @return string   返回文件全路径
 * @throws PHPExcel_Exception
 * @throws PHPExcel_Reader_Exception
 */
function exportExcel($title=array(), $data=array(), $fileName="", $savePath="./", $isDown=false){
	include("PHPExcel.php");
	$obj = new PHPExcel();

	//横向单元格标识
	$cellName = 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", "AA", "AB", "AC", "AD", "AE", "AF", "AG", "AH", "AI", "AJ", "AK", "AL", "AM", "AN", "AO", "AP", "AQ", "AR", "AS", "AT", "AU", "AV", "AW", "AX", "AY", "AZ");
	
	$obj->getActiveSheet(0)->setTitle("sheet名称");   //设置sheet名称
	$_row = 1;   //设置纵向单元格标识
	if($title){
		$_cnt = count($title);
		$obj->getActiveSheet(0)->mergeCells("A".$_row.":".$cellName[$_cnt-1].$_row);   //合并单元格
		$obj->setActiveSheetIndex(0)->setCellValue("A".$_row, "数据导出：".date("Y-m-d H:i:s"));  //设置合并后的单元格内容
		$_row++;
		$i = 0;
		foreach($title AS $v){   //设置列标题
			$obj->setActiveSheetIndex(0)->setCellValue($cellName[$i].$_row, $v);
			$i++;
		}
		$_row++;
	}

	//填写数据
	if($data){
		$i = 0;
		foreach($data AS $_v){
			$j = 0;
			foreach($_v AS $_cell){
				$obj->getActiveSheet(0)->setCellValue($cellName[$j] . ($i+$_row), $_cell);
				$j++;
			}
			$i++;
		}
	}
	
	//文件名处理
	if(!$fileName){
        $fileName = uniqid(time(),true);
    }

	$objWrite = PHPExcel_IOFactory::createWriter($obj, "Excel2007");

	if($isDown){   //网页下载
		header("pragma:public");
		header("Content-Disposition:attachment;filename=$fileName.xls");
        $objWrite->save("php://output");exit;
	}

	$_fileName = iconv("utf-8", "gb2312", $fileName);   //转码
	$_savePath = $savePath.$_fileName.".xlsx";
	 $objWrite->save($_savePath);

	 return $savePath.$fileName.".xlsx";
}

//exportExcel(array("姓名","年龄"), array(array("a",21),array("b",23)), "档案", "./", true);

2、PHPExcel导入方法实现过程

/**
*  数据导入
* @param string $file excel文件
* @param string $sheet
 * @return string   返回解析数据
 * @throws PHPExcel_Exception
 * @throws PHPExcel_Reader_Exception
*/
function importExecl($file="", $sheet=0){
	$file = iconv("utf-8", "gb2312", $file);   //转码
	if(empty($file) OR !file_exists($file)) {
		die("file not exists!");
	}
	include("PHPExcel.php");  //引入PHP EXCEL类
	$objRead = new PHPExcel_Reader_Excel2007();   //建立reader对象
	if(!$objRead->canRead($file)){
		$objRead = new PHPExcel_Reader_Excel5();
		if(!$objRead->canRead($file)){
			die("No Excel!");
		}
	}

	$cellName = 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", "AA", "AB", "AC", "AD", "AE", "AF", "AG", "AH", "AI", "AJ", "AK", "AL", "AM", "AN", "AO", "AP", "AQ", "AR", "AS", "AT", "AU", "AV", "AW", "AX", "AY", "AZ");

	$obj = $objRead->load($file);  //建立excel对象
	$currSheet = $obj->getSheet($sheet);   //获取指定的sheet表
	$columnH = $currSheet->getHighestColumn();   //取得最大的列号
	$columnCnt = array_search($columnH, $cellName);
	$rowCnt = $currSheet->getHighestRow();   //获取总行数

	$data = array();
	for($_row=1; $_row<=$rowCnt; $_row++){  //读取内容
		for($_column=0; $_column<=$columnCnt; $_column++){
			$cellId = $cellName[$_column].$_row;
			$cellValue = $currSheet->getCell($cellId)->getValue();
             //$cellValue = $currSheet->getCell($cellId)->getCalculatedValue();  #获取公式计算的值
			if($cellValue instanceof PHPExcel_RichText){   //富文本转换字符串
				$cellValue = $cellValue->__toString();
			}

			$data[$_row][$cellName[$_column]] = $cellValue;
		}
	}

	return $data;
}
