XML
- Use simplexml_load_string() to parse and pass an XML file to a variable. This function (and its associates) makes it extremely easy to deal with XML content.
- If we know the structure of the XML content we can simply refer to the data in the content via the XML’s file tree structure and element names.
e.g.
$xml_var->lvl1_name->lvl2_name->item_we_want
