is there a way to get the xml value by curly brackets?

For example I want to get the value of test->test_test and want to archieve this with the xml object variable. The path of the value inside the xml object comes from the database.

$xml_path = 'test->test_test';
    
echo $xml_obj->{$xml_path};

Also not working:

$xml_path = '{test}->{test_test}';
            
echo $xml_obj->{$xml_path};

Here I got the following error:

Serialization of 'SimpleXMLElement' is not allowed

  • Added a better example. – yfain Nov 08 '21 at 11:18
  • You might have to cast it to a string. Try echo (String) $xml_obj->{$xml_path}; – lukas.j Nov 08 '21 at 11:23
  • Makes no differences, because this is only then for the result. – yfain Nov 08 '21 at 11:44
  • The curly bracket syntax allows you to access _one_ property by its name put inside a variable, but it does not allow you to "jump" multiple `->` in one go. – CBroe Nov 08 '21 at 11:49
  • You probably want a solution similar to https://stackoverflow.com/questions/9628176/using-a-string-path-to-set-nested-array-data, only for objects instead of arrays. – CBroe Nov 08 '21 at 11:50
  • @CBroe Yes, I need to jumpe over multiple -> .. I will look at the solution. Thanks. – yfain Nov 08 '21 at 11:56
