$xml = simplexml_load_file('path_to_the_file');

Sometimes you’d need to dump or save the entire XML as a string, but there’s no toString method! As you can see $xml is an instance of the SimpleXMLElement class.

var_dump($xml); // object(SimpleXMLElement)...

Actually if you take a closer look:

$xml->toString();

will return “Call to an undefined method toString()”, which is frustrating because the developers community is used to use toString() when converting an object into a string.

The solution

In fact there’s a method doing exactly what’s needed. This is SimpleXMLElement::asXML

As described in the manual page: “SimpleXMLElement::asXML — Return a well-formed XML string based on SimpleXML element” [2].

Besides that it does exactly what’s needed it sounds irrelevant, because you’ve an XML object and the name “asXML” doesn’t describe correctly what’s expected.

$xml->asXML() // ?!
