How to output specific data in json array?

Question

PHP

There is an application that works with instagram without api, where in the search via curl data is taken from the instagram search
, here is the data

. Curl code:

public function fetchData($url){
        try {
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
            curl_setopt($ch, CURLOPT_TIMEOUT, 20);
            $result = json_decode(curl_exec($ch), true);
            curl_close($ch);
            return $result;
        } catch(Exception $e) {
            return $e->getMessage();
        }
    }

Search code:

public function getSearchProfiles($ignore=null) {
        $url = 'https://www.instagram.com/web/search/topsearch/?context=blended&query='.str_replace(' ', '.', $this->query).'&rank_token=';
        $result = $this->fetchData($url);
        $this->data['profiles'] = $result;        

        if($ignore != null) {
            foreach($this->data['profiles'] as $subKey => $subArray){
                if($subArray['username'] == $ignore){
                    unset($this->data['profiles'][$subKey]);
                }
            }
        }
    }

But when outputting data, the following error occurs Warning: Illegal string offset. What to do?

Answer 1

Everything tells you correctly, if in $this->data['profiles'] what you have in the screenshot, then there is no "username" key in this array. There are several nested arrays, and to get to "username" you need to iterate through them all.
