編輯自定義配置文件在網上笨

Question

我創造了我的編輯自定義配置文件 它`工作的成功，除了文件目錄的模型

這是我的模型

class Settings_model extends CI_Model{ 

    // replace config items 
    public function edit_line($word, $replace) { 
     $base_url = $this->config->base_url(); 
     $reading = fopen('../application/config/config_custom.php', 'r'); 
     $writing = fopen('../application/config/myconf_tmp.php', 'w'); 

     $replaced = false; 

     while (!feof($reading)) { 
      $line = fgets($reading); 
      if (stristr($line, $word)) { 
      $line = " '$word' => '$replace',\n"; 
      $replaced = true; 
      } 
      fputs($writing, $line); 
     } 
     fclose($reading); fclose($writing); 
     // might as well not overwrite the file if we didn't replace anything 
     if ($replaced) 
     { 
      rename($writing, $reading); 
     } else { 
      unlink($writing); 
     } 

    } 

} 

和我的控制器

class Settings extends My_Controller { 

    public function __construct() { 
     parent::__construct(); 
    } 

    public function index() { 

     if($this->input->post()) { 
      foreach($this->input->post() as $key => $value){ 
       $edit = $this->Settings_model->edit_line($key, $value); 
       echo $edit; 
      } 
     } 

     // Load View 
     $data['main_content'] = 'settings/index'; 
     $this->load->view('layouts/main',$data); 
    } 

} 

and view

<form action="<?php echo base_url().'settings/index';?>" method="post"> 
     <?php foreach($this->global_data as $key => $val):?> 
     <div class="form-group"> 
      <label><?=$key?></label> 
      <input type="text" name="config_item['<?=$key?>']'" class="form-control" value="<?=$val?>" /> 
     </div> 
     <?php endforeach; ?> 
     <button class="btn btn-success" type="submit">حفظ</button> 
</form> 

當我後我的形式，我收到此錯誤信息

A PHP Error was encountered 

Severity: Warning 

Message: fopen(../application/config/config_custom.php): failed to open stream: No such file or directory 

Filename: models/settings_model.php 

Line Number: 7 

什麼是我應該設置在型號爲我的配置文件路徑 請任何幫助，正確的路徑！

Insread此，

fopen('../application/config/config_custom.php', 'r'); 

嘗試使用這樣的，

fopen(APPPATH.'/config/config_custom.php', 'r');
