php - Multiple responses from function -

i'm trying have function return multiple results in array(?).

so instead of running lookup("354534", "name"); , lookup("354534", "date"); mutiple times different results, how can return both name & date function, echo out have use function once?

    function lookup($data, $what)  {   $json = file_get_contents("http://site.com/".$data.".json");   $output = json_decode($json, true);     echo $output['foo'][''.$what.''];  } 

thanks!

have function return whole json result:

function lookup($data) {     $json = file_get_contents("http://site.com/".$data.".json");     $output = json_decode($json, true);       return $output["foo"]; } 

then can

$result = lookup("354534");  echo $result["name"]; echo $result["date"]; 

this idea, because otherwise, you'll make (slow) file_get_contents request multiple times, want avoid.
