php 结合PHPExcel插件实现导入和导出功能

 

准备工作:
1.下载PHPExcel的SDK,下载地址: https://github.com/PHPOffice/PHPExcel

2.将SDK解压之后的Class文件拷贝到自己的项目。

 

1.0：Excel文件的数据读取，

function ExcelToArray($filename){
	 header("Content-type: text/html; charset=utf-8");
     require_once APP_ROOT."/extensions/phpexcel/PHPExcel.php";
	
	//加载excel文件
	$objPHPExcelReader = PHPExcel_IOFactory::load($filename);  
 
	$sheet = $objPHPExcelReader->getSheet(0); 		// 读取第一个工作表(编号从 0 开始)
	$highestRow = $sheet->getHighestRow(); 			// 取得总行数
	$highestColumn = $sheet->getHighestColumn(); 	// 取得总列数
 
	$arr = 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');
	// 一次读取一列
	$res_arr = array();
	for ($row = 2; $row <= $highestRow; $row++) {
		$row_arr = array();
		for ($column = 0; $arr[$column] != 'F'; $column++) {
			$val = $sheet->getCellByColumnAndRow($column, $row)->getValue();
			$row_arr[] = $val;
		}
		
		$res_arr[] = $row_arr;
	}
	
	return $res_arr;
}

1.1：或者

function ExcelToArray($filename){
	  header("Content-type: text/html; charset=utf-8");
      require_once APP_ROOT."/extensions/phpexcel/PHPExcel.php";
	//加载excel文件
	$objPHPExcelReader = PHPExcel_IOFactory::load($filename);  
 
	$reader = $objPHPExcelReader->getWorksheetIterator();
	//循环读取sheet
	foreach($reader as $sheet) {
		//读取表内容
		$content = $sheet->getRowIterator();
		//逐行处理
		$res_arr = array();
		foreach($content as $key => $items) {
			
			 $rows = $items->getRowIndex();    			//行
			 $columns = $items->getCellIterator();		//列
			 $row_arr = array();
			 //确定从哪一行开始读取
			 if($rows < 2){
				 continue;
			 }
			 //逐列读取
			 foreach($columns as $head => $cell) {
				 //获取cell中数据
				 $data = $cell->getValue();
				 $row_arr[] = $data;
			 }
			 $res_arr[] = $row_arr;
		}
		
	}
	
	return $res_arr;
}

以上两种方法均可读取Excel文件内容保存在一个多维数组中，然后就可以进行操作了。

2.0：Excel 数据导出（无模板）。

3.2：前端页面

3.3：前端代码。

    
    
    
    
    
    







    附件的上传类型： xlsx,xls




    


        

            导入数据：
            

                选择文件
            
        

        

                文件地址：
                

                    
                
        
        

            

                立即提交
            
        

    

除此之外表格还可以做很多的属性操作，有兴趣的可以去了解。
