How to use a foreach statement to loop through json search engine results?

[the5thace]

Sample query: http://www.faroo.com/api?q=elephants&start=1&length=10&l=en&src=web&f=json&jsoncallback=mycallback

 

I do not quite understand the parameters I need to use for a foreach statement to work on this query. 

 

Previously I have managed the foreach to loop through Blekko results sets with

 

 

foreach ($js->RESULT as $item)
         {  if(@$item->snippet || @$item->url_title)
         {$Blekko[$i] = "<a href=\"{$item->url}\"> 
         {$item->url_title}</a>blekko     
          <p>$item->snippet}</p>"; 

 

 but I'm not sure how it actually works. Bing query : https://api.datamarket.azure.com/Bing/Search/Web?$format=json&Query=%27bing%27

Whatever variable you're json_decode()ing to,

$obj = json_decode(/* whatever */);

$obj->results is the array of results
$obj->results[0] is the first one in that array
$obj->results[0]->title is the first title

I understand that but how do you know which variable offers the array of results? 

My current foreach does not work for the faroo query. Giving me an error on the foreach line.

foreach ($js->results as $item)
        {
            $Faroo[$i] = "<a href=\"{$item->url}\"> 
            {$item->title}</a>faroo  
            <p>$item->kwic}</p>";    
            $i++;

Wrong query given. I meant to give Blekko query: http://blekko.com/?q=dogs+/json+/ps=100&auth=

And that's a different JSON. Example:

$js->RESULT
$js->RESULT[0]
$js->RESULT[0]->url_title
