title: Double Quote Problem after Saving an INI file with Zend_Config
body: <p>I got a problem when I want to write and save an INI file. I use Zend_Config_Ini to handle this procedure. </p>
  
  <p>The problem is I always got 'Double Quote' in the value for every line that use integer or number afer saving process. Here is the example</p>
  
  <p>The original application.ini file</p>
  
  <pre><code>resources.session.use_only_cookies = 1
  resources.session.remember_me_seconds = 86400
  </code></pre>
  
  <p>After I run these lines of code</p>
  
  <pre><code>$config = new Zend_Config_Ini(APPLICATION_PATH . '/configs/application.ini',
                                        null,
                                        array('skipExtends'        =&gt; true,
                                              'allowModifications' =&gt; true));
  
          // Modify a value
  $config-&gt;production-&gt;resources-&gt;db-&gt;adapter = 'foobar';
  
          // Write the config file
  $writer = new Zend_Config_Writer_Ini(array('config' =&gt; $config,
                                             'filename' =&gt; APPLICATION_PATH . '/configs/application.ini'));
  $writer-&gt;write();
  </code></pre>
  
  <p>The application.ini lines become</p>
  
  <pre><code>resources.session.use_only_cookies = "1"  //double quote appears T_T
  resources.session.remember_me_seconds = "86400"  //double quote appears T_T
  </code></pre>
  
  <p>What I want is the integer value must still remain the same (without double quotes). </p>
  
  <p>Anyone can help me to solve this problem? </p>
  
  <p>Thank you very much in advance</p>
