title: Use `or` inside an `if` statment
body: <p>I don't know why this isn't working, in the database field <code>statuss</code>, the is <code>8</code>. And I am getting the output <code>You cannot do that!</code> from the bellow code:</p>
  
  <pre><code>if ( $o['statuss'] !== 1 || $o['statuss'] !== 8 ) {
    $ret['result_msg'] = 'You cannot do that!';
    die(json_encode($ret));
  }
  </code></pre>
  
  <p>I already tried, but to no avail:</p>
  
  <pre><code>if ( ($o['statuss'] !== 1) || ($o['statuss'] !== 8) )
  </code></pre>
  
  <p>If I leave only <code>if ( $o['statuss'] !== 8 )</code> then all works like expected.</p>
