How to display XML in HTML in PHP?

If the string is pre-formatted, and a plain text representation of the same is needed, it can be wrapped in a HTML <pre/> tag and html entities can be used to escape the angle brackets. This has been shown below −

<?PHP echo '<pre>', htmlentities($string), '</pre>'; ?>

The string is assigned to a string type and the above is used to show XML in HTML −

Example

<?php
$string = "
<example>
   <example>
      <example_value>EXAMPLE</example_value>
   </example>
</example> ";
echo '<pre>', htmlentities($string), '</pre>';
?>

Output

This will produce the following output −

<example>
   <example>
      <example_value>EXAMPLE</example_value>
   </example>
</example>
