使用PHPExcel实现Excel文件的导入和导出(模板导出)

在之前有写过一篇文章讲述了使用PHP快速生成excel表格文件并下载,这种方式生成Excel文件,生成速度很快,但是有缺点是:
1.单纯的生成Excel文件,生成的文件没有样式,单元格属性(填充色,宽度,高度,边框颜色...)不能自定义;
2.生成的文件虽然可以打开,但是兼容性很差,每次打开,都会报一个警告:

今天使用一个第三方的SDK(PHPExcel)实现Excel文件的导入和导出。

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。

一.Excel文件读取

复制代码
function excelToArray(){  
    require_once dirname(__FILE__) . "/Lib/Classes/PHPExcel/IOFactory.php";  
      
    //加载excel文件  
    $filename = dirname(__FILE__)."/result.xlsx";  
    $objPHPExcelReader = PHPExcel_IOFactory::load($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;  
}  
复制代码

或者:

复制代码
function excelToArray(){  
    require_once dirname(__FILE__) . "/Lib/Classes/PHPExcel/IOFactory.php";  
      
    //加载excel文件  
    $filename = dirname(__FILE__)."/result.xlsx";  
    $objPHPExcelReader = PHPExcel_IOFactory::load($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();              //
             $columns = $items->getCellIterator();       //
             $row_arr = array();  
             //确定从哪一行开始读取  
             if($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;  
}

两种方法均可将表格数据转化为数组,然后哦再进行相关的操作就简单了。

 

二.Excel文件导出

 

复制代码
/** 
 * 创建(导出)Excel数据表格 
 * @param  array   $list        要导出的数组格式的数据 
 * @param  string  $filename    导出的Excel表格数据表的文件名 
 * @param  array   $indexKey    $list数组中与Excel表格表头$header中每个项目对应的字段的名字(key值) 
 * @param  array   $startRow    第一条数据在Excel表格中起始行 
 * @param  [bool]  $excel2007   是否生成Excel2007(.xlsx)以上兼容的数据表 
 * 比如: $indexKey与$list数组对应关系如下: 
 *     $indexKey = array("id","username","sex","age"); 
 *     $list = array(array("id"=>1,"username"=>"YQJ","sex"=>"男","age"=>24)); 
 */  
function exportExcel($list,$filename,$indexKey,$startRow=1,$excel2007=false){  
    //文件引入  
    require_once APP_ROOT."/Api/excel/PHPExcel.php";  
    require_once APP_ROOT."/Api/excel/PHPExcel/Writer/Excel2007.php";  
      
    if(empty($filename)) $filename = time();  
    if( !is_array($indexKey)) return false;  
      
    $header_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");  
    //初始化PHPExcel()  
    $objPHPExcel = new PHPExcel();  
      
    //设置保存版本格式  
    if($excel2007){  
        $objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);  
        $filename = $filename.".xlsx";  
    }else{  
        $objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);  
        $filename = $filename.".xls";  
    }  
      
    //接下来就是写数据到表格里面去  
    $objActSheet = $objPHPExcel->getActiveSheet();  
    //$startRow = 1;  
    foreach ($list as $row) {  
        foreach ($indexKey as $key => $value){  
            //这里是设置单元格的内容  
            $objActSheet->setCellValue($header_arr[$key].$startRow,$row[$value]);  
        }  
        $startRow  ;  
    }  
      
    // 下载这个表格,在浏览器输出  
    header("Pragma: public");  
    header("Expires: 0");  
    header("Cache-Control:must-revalidate, post-check=0, pre-check=0");  
    header("Content-Type:application/force-download");  
    header("Content-Type:application/vnd.ms-execl");  
    header("Content-Type:application/octet-stream");  
    header("Content-Type:application/download");;  
    header("Content-Disposition:attachment;filename=".$filename."");  
    header("Content-Transfer-Encoding:binary");  
    $objWriter->save("php://output");  
}  
复制代码

导出文件,还可以设置模板

复制代码
function exportExcel($list,$filename,$indexKey=array()){  
    require_once dirname(__FILE__) . "/Lib/Classes/PHPExcel/IOFactory.php";  
    require_once dirname(__FILE__) . "/Lib/Classes/PHPExcel.php";  
    require_once dirname(__FILE__) . "/Lib/Classes/PHPExcel/Writer/Excel2007.php";  
      
    $header_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");  
      
    //$objPHPExcel = new PHPExcel();                        //初始化PHPExcel(),不使用模板  
    $template = dirname(__FILE__)."/template.xls";          //使用模板  
    $objPHPExcel = PHPExcel_IOFactory::load($template);     //加载excel文件,设置模板  
      
    $objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);  //设置保存版本格式  
      
    //接下来就是写数据到表格里面去  
    $objActSheet = $objPHPExcel->getActiveSheet();  
    $objActSheet->setCellValue("A2",  "活动名称:江南极客");  
    $objActSheet->setCellValue("C2",  "导出时间:".date("Y-m-d H:i:s"));  
    $i = 4;  
    foreach ($list as $row) {  
        foreach ($indexKey as $key => $value){  
            //这里是设置单元格的内容  
            $objActSheet->setCellValue($header_arr[$key].$i,$row[$value]);  
        }  
        $i  ;  
    }  
      
    // 1.保存至本地Excel表格  
    //$objWriter->save($filename.".xls");  
      
    // 2.接下来当然是下载这个表格了,在浏览器输出就好了  
    header("Pragma: public");  
    header("Expires: 0");  
    header("Cache-Control:must-revalidate, post-check=0, pre-check=0");  
    header("Content-Type:application/force-download");  
    header("Content-Type:application/vnd.ms-execl");  
    header("Content-Type:application/octet-stream");  
    header("Content-Type:application/download");;  
    header("Content-Disposition:attachment;filename="".$filename.".xls"");  
    header("Content-Transfer-Encoding:binary");  
    $objWriter->save("php://output");  
}  
复制代码

先弄一个excel模板

然后使用该模板导出数据

除此之外还可以对表格属性做很多自定义。感兴趣的自己看看吧!
