Convert the well-formed XML document in the given file to an object.
filename
Path to the XML file
Note: Libxml 2 unescapes the URI, so if you want to pass e.g. b&c as the URI parameter a, you have to call simplexml_load_file(rawurlencode('http://example.com/?a=' . urlencode('b&c'))). Since PHP 5.1.0 you don't need to do this because PHP will do it for you.
class_name
You may use this optional parameter so that simplexml_load_file() will return an object of the specified class. That class should extend the SimpleXMLElement class.
options
Since PHP 5.1.0 and Libxml 2.6.0, you may also use the
options
parameter to specify additional Libxml parameters.
ns
is_prefix
Returns an object of class SimpleXMLElement with properties containing the data held within the XML document. On errors, it will return FALSE.
