php - Iterating through an associative array -

-

i trying twitter followers specific user api call

https://api.twitter.com/1/users/lookup.json?screen_name=twitterapi,twitter&include_entities=true

and there sample output there: 

https://dev.twitter.com/docs/api/1/get/users/lookup

i trying screen name of user doing following:

$json2=file_get_contents('http://api.twitter.com/1/users/lookup.json?user_id='.$post.'') ;  $accounts2 = json_decode($json2);  while( $element = each( $accounts2 ) ) {   echo $element[ 'screen_name' ];   echo '<br />'; }

where $post ids (around 100) concatenated together.

the above fail with:

notice: trying property of non-object

any please?

replace line:

$accounts2 = json_decode($json2);

with this:

$accounts2 = json_decode($json2, true);

it converts associative array. because user_id unique, don't have loop through results, can this:

echo $accounts2[0]['screen_name'] . '<br />';
