PHP SQL, query returns only one row of data

A friend of mine is asked me to do some coding. He created a MySQL database with columns “gameName” (VARCHAR) and “releaseDate” (date). He needs to fetch and show the game names from “gameName” which are released before current date.

Here I have used MySQL’s CURDATE() function to filter out already released games. But the problem is I have to write an echo line for each results. It’s bad programming and the logic behind that is very bad.

<?php
$mysql_host="host_name";
$mysql_username="db_user";
$mysql_password="db_password";
$mysql_database="db_name";
$mysql_table="table_name";

mysql_connect("host_name", "db_user", "db_password") or die("YOLO");
mysql_select_db("db_name") or die("YOLO");

$sql = mysql_query("SELECT gameName FROM table_name WHERE CURDATE() > releaseDate");
$result = mysql_fetch_row($sql);

echo $result[0];
echo $result[1];
echo $result[2];
// and so on...?
?>

Result: Only one record showed up.

PDO example,

   $config = array(
        'host'  => 'hostname',
        'db'    => 'db_name',
        'user'  => 'db_user',
        'pass'  => 'db_pass'
    );

    try{

        $PDO = new PDO(
            'mysql:host='.$config['host'].';dbname='.$config['db'],
            $config['user'],
            $config['pass']
        );

        $query = $PDO->query("
                    SELECT id FROM table_name WHERE CURDATE() > releaseDate"
            );
        $query->setFetchMode(PDO::FETCH_OBJ);
        while($game = $query->fetch()){
            echo $game->gameName;
        }   

    }catch(PDOException $e){
        echo $e->getMessage();
    }
    unset($PDO);
