PHP JSON foreach Array Issue -

i'm trying use php display json data api. need use foreach return results nested within them array. array "highlights" has "description" , "content" , both. need foreach within foreach or along lines try returns "array".

here's json...

https://api.data.gov/gsa/fbopen/v0/opps?q=lte+test+bed+system&data_source=fbo&limit=100&show_closed=true&api_key=ctrs3pcyimtdr4wkn50ai1gcuxyl9m4s1fybbser

here's php...

$json_returned = file_get_contents("json_url"); $decoded_results = json_decode($json_returned, true);  echo "number found:".$decoded_results['numfound']."</br> "; echo "start:".$decoded_results['start']."</br>"; echo "max score:".$decoded_results['maxscore']."</br>";  foreach($decoded_results['docs'] $results){ echo "parent link t:".$results['parent_link_t']."</br>"; echo "description:".$results['highlights']['description']."</br>"; } 

obviously working version i'm using has lot more fields programmed in cut them out keep code short , simple , show how have else besides "hightlights" field in 1 foreach. json returns require keep in foreach, how display array inside of it?

thanks , taking time read if can contribute.

the 'description' array 1 element can use this.

echo 'description:' . $results['highlights']['description'][0]; 

if has 'description' , 'content'. use isset check 1 is, or if there both , print accordingly.

// description if(isset($results['highlights']['description'])) {    echo 'description:' . $results['highlights']['description'][0]; } // content if(isset($results['highlights']['content'])) {    echo 'content:' . $results['highlights']['content'][0]; } 

hope helps.
