Are there any best practices for structuring PHP code to handle multiple groups in a tournament scenario?

When structuring PHP code to handle multiple groups in a tournament scenario, it is important to organize the data in a way that allows for easy manipulation and retrieval of information for each group. One way to achieve this is by using arrays to store the groups and their respective teams. By creating functions to add teams to groups, update match results, and display standings, you can effectively manage the tournament scenario.

<?php

// Define an array to store the groups and their teams
$groups = [];

// Function to add a team to a group
function addTeamToGroup($group, $team) {
    global $groups;
    if (!isset($groups[$group])) {
        $groups[$group] = [];
    }
    $groups[$group][] = $team;
}

// Function to update match results
function updateMatchResult($group, $team1, $team2, $result) {
    global $groups;
    // Update match result logic here
}

// Function to display standings for a group
function displayStandings($group) {
    global $groups;
    // Display standings logic here
}

// Example usage
addTeamToGroup('Group A', 'Team 1');
addTeamToGroup('Group A', 'Team 2');
addTeamToGroup('Group B', 'Team 3');

updateMatchResult('Group A', 'Team 1', 'Team 2', '1-0');

displayStandings('Group A');
