                    },
                    "xml_base": "",
                    "xml_base_explicit": false,
                    "xml_lang": "",
                    "child": {
                        "": {
                            "channel": [{
                                "data": "\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n ",

There are two ways to access the title object, dependent on whether you decode the JSON as an object or as an array. If you decode as an object, you need to use the ->{'element'} notation to get around the empty names (Note this only works in PHP 7.2 and higher):

$json = json_decode($jsonstr);
print_r($json->child->{''}->rss[0]->child->{''}->channel[0]->child->{''}->title);

Output:

Array ( 
    [0] => stdClass Object (
         [data] => Data name
         [attribs] => Array ( )
         [xml_base] =>
         [xml_base_explicit] =>
         [xml_lang] => 
    )
)

As an array you just need to use a blank index (''):

$json = json_decode($jsonstr, true);
print_r($json['child']['']['rss'][0]['child']['']['channel'][0]['child']['']['title']);

Output:

Array ( 
    [0] => Array (
        [data] => Data name
        [attribs] => Array ( )
        [xml_base] =>
        [xml_base_explicit] =>
        [xml_lang] =>
    ) 
)

                                            "xml_lang": ""
                                        }]
                                    }

                                }
                            }]

                    }
                }]
            }
        }
    }';
