I am able to extract the id from the above array,but unable to extract the count of likes and message.

Answer 1

Try this code, it iterates in your array and stores all ids and stores the message, the likes Array and the number of likes only if they exist (Supposing that your array is named $myarray):

$result = array();

foreach($myarray['data'] as $data){

    $item = array();

    $item['id'] = $data['id'];

    if( isset($data['message']) || isset($data['likes']) ){

        if(isset($data['message'])) $item['message'] = $data['message'];

        if(isset($data['likes'])) {

            $item['likes'] = array();

            foreach($data['likes']['data'] as $like){

                $item['likes'][] = $like['id'];

            }

            $item['countlikes'] = count( $data['likes']['data'] );

        }

    }

    $result[] = $item;

}

print_r($result);

With your example Array the result will be:

Array

    [0] => Array
