Why does MongoDB 3.0 throw an error when trying to get records?

Question

PHP

<?php
$m = new MongoClient(); // соединение
$db = $m->test; 
$db->shows->insert( ["item" => "card", "qty" => 15] );
  echo $a = $db->shows->find();
?>

Catchable fatal error: Object of class MongoCursor could not be converted to string in /var/www/html/index.php on line 14

Answer 1

Apparently the cursor needs to be sorted out in a loop, or at least converted to an array before displaying.
