SimpleXml to string

To convert a SimpleXml object to a string in PHP, you can use the asXML() function. For example:

<?php

$xml = new SimpleXmlElement('<example>Hello World</example>');
$string = $xml->asXML();

echo $string;

This will convert the $xml object to a string with the contents <example>Hello World</example>.

Alternatively, you can also use the saveXML() function, which accepts an optional parameter for the node to return as a string.

<?php

$xml = new SimpleXmlElement('<example>Hello World</example>');
$string = $xml->saveXML();

echo $string;

Both asXML() and saveXML() will convert the entire SimpleXml object to a string.
