title: php variable assign as false value
body: <pre><code>class Email
  {       
      var $to = false;
      var $subject = false;   
  }
  </code></pre>
  
  <p>I am a beginner in PHP. I have a class <code>Email</code>. In that class my variable <code>$to</code> gets assigned to <code>false</code> initially. It will be assigned to a value that is storred in another variable. I don't understand why this variable has this initial <code>false</code> value.</p>
  
  <p>Can you please explain me why</p>
