i trying print in echo each student average score right stuck got warning array string convertion can give me hint how suppose loop.

use php-functions calculate average every student, rounded 2 digits: 

foreach($student $std) {      $avg = round(array_sum($std['score']) / count($std['score']), 2);     echo $std['name']. ": $avg <br />"; }
