示例 #1 Interpret an XML document
<?php
// The file test.xml contains an XML document with a root element
// and at least an element /[root]/title.
if (file_exists('test.xml')) {
$xml = simplexml_load_file('test.xml');
print_r($xml);
} else {
exit('Failed to open test.xml.');
}
?>
This script will display, on success:
SimpleXMLElement Object ( [title] => Example Title ... )
At this point, you can go about using $xml->title
and any other elements.
