Where do you get that json from? It would be easier to fix that. — M. Eriksson, Dec 04 '18 at 06:17
Let me guess - is this some XML to array output. If you stick with using XML there are all sorts of resources for that - https://stackoverflow.com/questions/18906366/parsing-an-rss-feed-in-php-with-dom, https://stackoverflow.com/questions/250679/best-way-to-parse-rss-atom-feeds-with-php — Nigel Ren, Dec 04 '18 at 07:07

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] =>
    ) 
)
