title: Use of undefined constant name assumed 'title' (this will throw an Error in a future version of PHP)
body: <p>I was following tutorials but this error is showing for this line. I am confused about what to do? It's saying it will give an error in the near future. I used this for the nav bar.</p>
  <pre><code> $navItems = array(
                        array(
                             slug =&gt; &quot;index.php&quot;,
                             title =&gt; &quot;Home&quot;,
                        ),
                          array(
                             slug =&gt; &quot;about.php&quot;,
                             title =&gt; &quot;About Us&quot;,
