title: How to print_r $_POST array?
body: <p>I have following table.</p>
  
  <pre><code>&lt;form method="post" action="test.php"&gt;
    &lt;input name="id[]" type="text" value="ID1" /&gt;
    &lt;input name="value[]" type="text" value="Value1" /&gt;
    &lt;hr /&gt;
  
    &lt;input name="id[]" type="text" value="ID2" /&gt;
    &lt;input name="value[]" type="text" value="Value2" /&gt;
    &lt;hr /&gt;
  
    &lt;input name="id[]" type="text" value="ID3" /&gt;
    &lt;input name="value[]" type="text" value="Value3" /&gt;
    &lt;hr /&gt;
  
    &lt;input name="id[]" type="text" value="ID4" /&gt;
    &lt;input name="value[]" type="text" value="Value4" /&gt;
    &lt;hr /&gt;
  
    &lt;input type="submit" /&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>And test.php file</p>
  
  <pre><code>&lt;?php 
  
    $myarray = array( $_POST);
    foreach ($myarray as $key =&gt; $value)
    {
      echo "&lt;p&gt;".$key."&lt;/p&gt;";
      echo "&lt;p&gt;".$value."&lt;/p&gt;";
      echo "&lt;hr /&gt;";
    }
  
  ?&gt;
  </code></pre>
  
  <p>But it is only returning this: <code>&lt;p&gt;0&lt;/p&gt;&lt;p&gt;Array&lt;/p&gt;&lt;hr /&gt;</code> </p>
  
  <p>What I'm doing wrong?</p>
