title: $_POST is returning just 'Array' as string and i am posting an Array
body: <p>It's a very strange error that i am facing.I have some html i.e below</p>
  
  <pre><code>&lt;input type="checkbox"  name="om[1]" value="10"&gt;
  &lt;input type="checkbox"  name="om[2]" value="20"&gt;
  &lt;input type="checkbox"  name="om[3]" value="30"&gt;
  </code></pre>
  
  <p>When i post this form and do </p>
  
  <pre><code>print_r($_POST['om'])
  it gives just prints 'Array' as string
  and if i do print_r($_POST['om'][0]) it gives A
  and if i do print_r($_POST['om'][1]) it gives r 
  </code></pre>
  
  <p>But if i do </p>
  
  <pre><code>print_r($_REQUEST['om'])
  it display a proper array
  
  Array
     (
      [1] =&gt; 10
      [2] =&gt; 20
      [3] =&gt; 30
    )
  </code></pre>
  
  <p>Problem is when i am using <strong>$_POST</strong> for getting array values it not displaying, it works fine if posted value is not in array.
  But i can get all the required result with <strong>$_REQUEST['om']</strong> even if they are array.</p>
  
  <p>And it's happening only on <strong>server</strong>, working fine for localhost.
  Can anybody tell what can be the problem on server??</p>
