title: PHP syntax and programmatical grammar explanation
body: <p>I have a piece of code that needed to be directly translated from PHP to vb.net/C#. I would like to ask, what do these next expressions meant in simple English terms? Maybe a little bit (or more) of an elaboration would be nice. Here goes.</p>
  
  <pre><code>1.    foreach ($_SESSION[''] as $variable1 =&gt; $variable2) {}
  2.    $variable .= &lt;&lt;&lt;EOD{ "a":"1", "b":"2","c":"3" },EOD
  </code></pre>
  
  <p>I would like to understand what they meant. And maybe a little advice on how to apply it in asp.net.</p>
