title: INI file to multidimensional array in PHP
body: <p>I have the next INI file:</p>
  
  <pre><code>a.b.c = 1
  a.b.d.e = 2
  </code></pre>
  
  <p>I am parsing this file using parse_ini_file. And it returns:</p>
  
  <pre><code>array(
      'a.b.c' =&gt; 1,
      'a.b.d.e' =&gt; 2
  )
  </code></pre>
  
  <p>But I want to create a multidimensional array. My outout should be:</p>
  
  <pre><code>array(
      'a' =&gt; array(
          'b' =&gt; array(
              'c' =&gt; 1,
              'd' =&gt; array(
                  'e' =&gt; 2
              )
          )
      )
  )
  </code></pre>
  
  <p>Thank you in advance.</p>
