What potential pitfalls should be considered when integrating a tournament bracket system into a web portal using PHP?

One potential pitfall to consider when integrating a tournament bracket system into a web portal using PHP is the complexity of managing and updating the bracket as matches are played and winners are determined. To solve this issue, it is important to have a structured database schema to store match results and update the bracket dynamically based on these results. 

// Sample code for updating match results in the database and dynamically updating the bracket

// Update match result in the database
$match_id = $_POST['match_id'];
$winner_id = $_POST['winner_id'];

$query = "UPDATE matches SET winner_id = $winner_id WHERE id = $match_id";
// Execute the query to update the match result in the database

// Dynamically update the bracket based on match results
// Query the database to get all matches in the bracket
$query = "SELECT * FROM matches";
// Execute the query to fetch all matches

// Loop through the matches and update the bracket display based on match results
foreach($matches as $match) {
    if($match['winner_id'] != null) {
        // Update the bracket display to show the winner of the match
    } else {
        // Display the match as upcoming or in progress based on match status
    }
}
