What are the potential drawbacks of using numbered columns for storing multiple team selections in a PHP application?

Using numbered columns for storing multiple team selections in a PHP application can make the code harder to read and maintain, as it may not be clear what each number represents. It can also limit the flexibility of the code if the number of team selections changes in the future. To solve this issue, it is recommended to use associative arrays with descriptive keys to store team selections. 

// Using associative arrays to store team selections
$teamSelections = [
    'team1' => ['player1', 'player2', 'player3'],
    'team2' => ['player4', 'player5', 'player6']
];

// Accessing team selections
echo "Team 1 players: " . implode(', ', $teamSelections['team1']);
echo "Team 2 players: " . implode(', ', $teamSelections['team2']);
