php 读取，生成excel文件

首先下载插件PHPExcel （PHPExcel-1.8），以tp5框架为例，将该文件放在verdor文件夹下。然后引入IOFactory文件。

1.读取文件的部分内容（用于固定格式）

 1 public function readExcel($filename){
 2             try {
 3                 Vendor(\'PHPExcel/PHPExcel/IOFactory\');
 4                 $reader = \PHPExcel_IOFactory::createReader(\'Excel2007\');
 5                 $PHPExcel = $reader->load($filename); // 文档名称
 6                 $objWorksheet = $PHPExcel->getActiveSheet();   #获取当前sheet
 7                 $highestRow = $objWorksheet->getHighestRow(); // 取得总行数
 8                 $highestColumn = $objWorksheet->getHighestColumn(); // 取得总列数
 9                 $data = array();
10                 for ($row = 1; $row <= $highestRow; $row++) {
11                     #从第二行开始，依次获取多少列的内容 因为第一行一般是表头 也可再加一个for循环 获取每一列的内容
12                     $A = $objWorksheet->getCellByColumnAndRow(0, $row)->getValue();
13                     $B = $objWorksheet->getCellByColumnAndRow(1, $row)->getValue();
14                     array_push($data,$A,$B);
15                 }
16                 return $data;
17             } catch (Exception $e) {
18                 $this->ajaxReturn(array(
19                     \'code\' => -1,
20                     \'msg\' => $e->getMessage()
21                 ));
22             }
23         }

readExcel

 

注：默认从第一行开始，读取A列和B列，以数组的形式返回，但是可以自定义。传入文件路径即可

 

2.读取文件的全部内容（用于多变，未知格式）

 1 public function excelread($path){
 2         try {
 3             Vendor(\'PHPExcel/PHPExcel/IOFactory\');
 4             $reader = \PHPExcel_IOFactory::createReader(\'Excel5\');
 5             $PHPExcel = $reader->load($path); // 文档名称
 6             $objWorksheet = $PHPExcel->getSheet(0);  #获取当前sheet
 7             $highestRow = $objWorksheet->getHighestRow(); // 取得总行数
 8             $highestColumn = $objWorksheet->getHighestColumn(); // 取得总列数
 9             $data =array();
10             for ($row = 1; $row <= $highestRow; $row++) {
11                 for ($col = \'A\'; $col != $highestColumn; $col ++) {
12                     #从第二行开始，依次获取多少列的内容 因为第一行一般是表头 也可再加一个for循环 获取每一列的内容
13                     $res = $objWorksheet->getCell($col.$row)->getValue();
14                     $res = mb_convert_encoding($res, "UTF-8", "GBK");
15                     $data[$col][$row] = $res;
16                 }
17             }
18             return $data;
19         } catch (Exception $e) {
20             $this->ajaxReturn(array(
21                 \'code\' => -1,
22                 \'msg\' => $e->getMessage()
23             ));
24         }
25     }

3.生成excel文件在线下载 

 #添加内容
    #$data=array(
    #    array(),
    #    array("","name","greate"),
    #    array("","xuzhan","12"),
    #    array("","paopao","24")
    #);
    public function excel_export($data)
    {
        try {
            Vendor(\'PHPExcel/PHPExcel/IOFactory\');
            $obj = new \PHPExcel();
            $objsheet=$obj->getActiveSheet();
#设置sheet的名称
            #$objsheet->setTitle("demo");
            $objsheet->fromArray($data);
#按照指定格式保存文件，保存文件
            header(\'Content-Type: application/vnd.ms-excel\');
//下载的excel文件名称，为Excel5，后缀为xls，不过影响似乎不大
            header(\'Content-Disposition: attachment;filename="\' . time() . \'.xlsx"\');
            header(\'Cache-Control: max-age=0\');
            $objWriter=\PHPExcel_IOFactory::createWriter($obj,"Excel2007"); //通过PHPExcel_IOFactory的写函数将上面数据写出来
            $objWriter->save(\'php://output\');
        } catch (Exception $e) {
            $this->ajaxReturn(array(
                \'code\' => -1,
                \'msg\' => $e->getMessage()
            ));
        }
    }

 4. 另外一种生成方式

public function excel_export($data)
    {
        try {
            Vendor(\'PHPExcel/PHPExcel/IOFactory\');
            $obj = new \PHPExcel();
            $objsheet=$obj->getActiveSheet();
            #设置sheet的名称
            #$objsheet->setTitle("demo");
            $objsheet->fromArray($data);
            #按照指定格式保存文件，保存文件
            header(\'Content-Type: application/vnd.ms-excel\');
            //下载的excel文件名称，为Excel5，后缀为xls，不过影响似乎不大
            header(\'Content-Disposition: attachment;filename="\' . time() . \'.xlsx"\');
            header(\'Cache-Control: max-age=0\');
            $objWriter=\PHPExcel_IOFactory::createWriter($obj,"Excel2007"); //通过PHPExcel_IOFactory的写函数将上面数据写出来
            $objWriter->save(\'php://output\');
        } catch (Exception $e) {
            $this->ajaxReturn(array(
                \'code\' => -1,
                \'msg\' => $e->getMessage()
            ));
        }
    }
