There is no need to do both, simplexml_load_file and create a new SimpleXML object.

simplexml_load_file already interprets an XML file into an object. (Keep in mind, it does not accept an XML string)

$movies = simplexml_load_file('test.xml');

Alternatively, you may directly load an XML string into a SimpleXML object.

$movies = new SimpleXMLElement(file_get_contents('test.xml'));

Either of the above approaches can be used to execute the following:

echo $movies->movie[0]->plot;

When you go to load XML data, there's two ways to do it. You either load the contents of the XML file as a string, then pass that string to Simple XML:

$fileContents = file_get_contents('test.xml'); # reads the file and returns the string

$xml = simplexml_load_string($fileContents); # creates a Simple XML object from a string

print_r($xml); # output is a Simple XML object

...or, you load the file directly into a Simple XML Object:

$xml = simplexml_load_file('test.xml'); # Instantiates a new Simple XML object from the file, without you having to open and pass the string yourself

print_r($xml); # output is a Simple XML object
