ReflectionExtension::getFunctions() example

<?php
$dom = new ReflectionExtension('SimpleXML');

print_r($dom->getFunctions());
?>

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
        )

)
