imported plaintext looses CRLF

Hello,
I am reading a plaintext file into CKEditor, but when displaying the content, all CRLF from the file is lost and I get every formatting lost...

Can anybody please have a look at this?

       $this->setAttrib('class', 'ckeditor');
       try {
          $appiniPath = APPLICATION_PATH . '/configs/application.ini';

          $resource = fopen($appiniPath, 'rb');  // b flag means read binary
          $appini = ""; 
          while ($rs = fgets($resource)) {
             $appini .= $rs . PHP_EOL;
          }
          
          $appini = htmlentities($appini) ;
          
          $this->setValue($appiniPath);
             $this->setValue($appini);
       } catch (Exception $e) {
             echo $e; 
       };
