You have been given the following code snippet:

<?php
 $string = <<<XML
 <?xml version="1.0" encoding="ISO-8859-1"?> 
 <email> 
 <to>jenny@ucertify.com</to> 
 <from>john@ucertify.com</from> 
 <heading>Technical issue in Linux OS</heading> 
 <body>There is a technical issue in my Linux system. Please Fix it. </body>
 </email> 
 XML;

 <Write code here> 
  ?>

Which of the following code snippets will you write to print the XML content?

$xml = load_XML($string); print_r($xml);

$xml = XML_string($string); print_r($xml);

$xml = simplexml_string($string); print_r($xml);

$xml = simplexml_load_string($string); print_r($xml);

Explanation: Answer option D is correct.

The simplexml_load_string() function is used to interpret a string of XML into an object. The syntax of the simplexml_load_string() function is as follows:

object simplexml_load_string ( string $data [, string $class_name = "SimpleXMLElement" [, int $options = 0 [, string $ns [, bool $is_prefix = false ]]]] )
