What are the key considerations for integrating PHP functions with HTML elements to display dynamic content in a web application?

When integrating PHP functions with HTML elements to display dynamic content in a web application, it is important to ensure that the PHP code is properly embedded within the HTML code using the <?php ?> tags. Additionally, the PHP functions should be used to retrieve dynamic data from a database or perform calculations, which can then be echoed within the HTML elements to display the content dynamically. 

&lt;?php
// Retrieve dynamic data from a database
$dynamic_content = &quot;Hello, World!&quot;;

// Display dynamic content within HTML elements
echo &quot;&lt;h1&gt;$dynamic_content&lt;/h1&gt;&quot;;
?&gt;
