What are some common pitfalls to avoid when combining PHP and JavaScript code within a <div> element for displaying dynamic content?

One common pitfall to avoid when combining PHP and JavaScript code within a <div> element is mixing server-side and client-side logic incorrectly. To solve this, separate the PHP code that generates dynamic content from the JavaScript code that manipulates it by using PHP to echo out data into HTML attributes or hidden elements, then have JavaScript retrieve and manipulate that data. 

&lt;div id=&quot;dynamicContent&quot; data-content=&quot;&lt;?php echo $dynamicContent; ?&gt;&quot;&gt;&lt;/div&gt;
&lt;script&gt;
  var dynamicContent = document.getElementById(&#039;dynamicContent&#039;).getAttribute(&#039;data-content&#039;);
  // Use dynamicContent in JavaScript code here
&lt;/script&gt;
