How to get real data inside XML?

Create the XML file: Test.xml, the PHP file that is stored in and read under the same level directory.

XML file:

1 <?XML version= "1.0" encoding= "UTF-8"?>2 <node>3     <ID>10001</ID>4     <UserName>Admin</UserName>5     <node>6         <token>Secretkey</token>7     </node>8 </node>

PHP Files:

1<?PHP2     $file= ' Test.xml ';3     $xml _object=simplexml_load_file($file);//reads the data from the XML into the array object4     Var_dump($xml _object);5     //All object Result collection6 //object (simplexmlelement) #1 (3) {["id"]=> string (5) "10001" ["UserName"]=> string (5) "admin" ["Node"]=> Object (SimpleXMLElement) #2 (1) {["token"]=> string (9) "Secretkey"}}7     Echo' <pre> ';8 9     Var_dump($xml _object-ID);Ten     //$xml _object->id Object Values One //object (simplexmlelement) #2 (1) {[0]=>string (5) "10001"} A     Echo' <pre> '; -  -     Echo($xml _object-ID); the     //$xml _object->id Object Values - //10001 (echo cast result) -     Echo' <pre> '; -  +     //note that getting real parameter values in the code requires us to do the cast processing -     Var_dump((string)$xml _object-ID); +     //$xml _object->id Object Values A //string (5) "10001" at     Echo' <pre> '; -  -     Var_dump((string)$xml _object->node->token); -     //$xml _object->node->token Object Values - //string (9) "Secretkey"
