CRUD operations with php

Complete the function to return a PDOStatement object containing the podcasts from a database. The function get_podcasts has been started for you, and contains a connection to the database. The connection object is named $db. In the database is a table named 'podcasts'.

index.php 
<?php
function get_podcasts() {
    include 'connection.php';
  try{
  return $db->query('SELECT podcats_id FROM podcasts');
  } catch (Exception $e){
  echo "Error!" . $e->getMessage() . "<br/>";
    return array ();
  }
$sql = 'SELECT podcats_id FROM podcasts';
    //add code here
try{
 $results = $db->prepare($sql);
  $results->execute();
} 
  catch (Exception $e) 
  {
echo "Error!: " . $e->getMessage() . "<br/>";
return false;
}
  return true;
}

The problem with this, is that you have a table called podcasts, but you do not know what or how many columns are in the table. So when you do the SELECT command, you have to put in the wildcard * character. That way, you will get all of the data. The answer should look something like this:

try {

    return $db->query('SELECT * FROM podcasts');
    } catch (PDOException $e) {
        echo "Error! " . $e->getMessage() . "</br>";
        return array();
        }

Hope this helps!
