<?php 

$json = '{"_type":"SearchResponse","queryContext":{"originalQuery":"infokart India Pvt. Ltd."},"webPages":{"webSearchUrl":"https://www.bing.com/search?q=infokart+India+Pvt.+Ltd.","totalEstimatedMatches":12200000,"value":[{"id":"https://api.cognitive.microsoft.com/api/v7/#WebPages.0","name":"Infokart India Pvt. Ltd.","url":"http://infokartindia.com/","isFamilyFriendly":true,"displayUrl":"infokartindia.com","snippet":"Journals Subscription Services,International Subscription Agency,Experiences subscription agency","dateLastCrawled":"2018-07-24T11:49:00.0000000Z","language":"en"}]},"rankingResponse":{"mainline":{"items":[{"answerType":"WebPages","resultIndex":0,"value":{"id":"https://api.cognitive.microsoft.com/api/v7/#WebPages.0"}}]}}}';

$json_data = json_decode($json,true);

foreach($json_data['webPages']['value'] as $each_data){
    foreach($each_data as $each_key => $each_value){
        if(in_array(strtolower($each_key),['url','displayurl','snippet'])){
            echo $each_key," => ",$each_value,"<br/>";
        }
    }
}

OUTPUT

url => http://infokartindia.com/
displayUrl => infokartindia.com
snippet => Journals Subscription Services,International Subscription Agency,Experiences subscription agency
