我想问一下如何将excel转换成pdf？

我想放5个excel文件，点击上传后转换为1个pdf？ p>

现在我在这段代码中使用：

  / ** 
 *示例：DOMPDF 
 * 
 *文档：
 * http://code.google.com/p/dompdf/wiki/Usage 
 * 
 * / 
 public function index（）{
 //以正常方式加载所有视图
 $ this-> load-> view（'test'）; 
 //获取输出html 
 $ html = $ this-> output-> get_output（）; 
 
 //加载库
 $ this-> load-> library（'dompdf_gen'）; 
 
 //转换为PDF 
 $ this-> dompdf-> load_html（$ html）; 
 $ this-> dompdf-> render（）; 
 $ this-> dompdf-> stream（welcome.pdf）; 
 
} 
  

图书馆：

class Dompdf_gen {

  public function __construct（）{
 
 require_once APPPATH。 'THIRD_PARTY / DOMPDF / dompdf_config.inc.php'; 
 
 $ pdf = new DOMPDF（）; 
 
 $ CI =& get_instance（）; 
 $ CI-> dompdf = $ pdf; 
 
} 
  

}

解决方案

第一件事情，你必须将所有excel转储到php数组或var，之后可以根据需要创建pdf，这是将excel转换为pdf的简单php脚本，你可以使用它并将其转换为代码标识符的子类

请检查此URL

当您使用该类时，您的excel数据将与您一起使用，因此您可以使用另一个类别的PDF，此类将帮助您

希望这对你有帮助。

I want to ask how can I convert excel to pdf?

I want to put 5 excel files and after I click upload in convert to 1 pdf?

for now I use in this code:

    /**
 * Example: DOMPDF 
 *
 * Documentation: 
 * http://code.google.com/p/dompdf/wiki/Usage
 *
 */
public function index() {   
    // Load all views as normal
    $this->load->view('test');
    // Get output html
    $html = $this->output->get_output();

    // Load library
    $this->load->library('dompdf_gen');

    // Convert to PDF
    $this->dompdf->load_html($html);
    $this->dompdf->render();
    $this->dompdf->stream("welcome.pdf");

}

the library:

class Dompdf_gen {

public function __construct() {

    require_once APPPATH.'third_party/dompdf/dompdf_config.inc.php';

    $pdf = new DOMPDF();

    $CI =& get_instance();
    $CI->dompdf = $pdf;

}

}
