The above example will output something similar to:

Array ( [simplexml_load_file] => ReflectionFunction Object ( [name] => simplexml_load_file )

[simplexml_load_string] => ReflectionFunction Object
    (
        [name] => simplexml_load_string
    )

[simplexml_import_dom] => ReflectionFunction Object
    (
        [name] => simplexml_import_dom
    )

)
