How can PHP developers ensure fairness in determining relegation candidates when multiple teams have equal points, goal differences, wins, and losses?

To ensure fairness in determining relegation candidates when multiple teams have equal points, goal differences, wins, and losses, PHP developers can implement a tiebreaker rule based on additional criteria such as head-to-head results, goals scored, or fair play points. By adding these tiebreaker rules, developers can create a more objective and transparent process for determining which teams should be relegated. 

// Sample PHP code for implementing tiebreaker rules for relegation candidates

// Define an array of teams with their points, goal differences, wins, losses, and additional tiebreaker criteria
$teams = [
    ['name' => 'Team A', 'points' => 30, 'goal_difference' => 10, 'wins' => 8, 'losses' => 6, 'head_to_head' => 2],
    ['name' => 'Team B', 'points' => 30, 'goal_difference' => 10, 'wins' => 8, 'losses' => 6, 'head_to_head' => 1],
    ['name' => 'Team C', 'points' => 30, 'goal_difference' => 10, 'wins' => 8, 'losses' => 6, 'head_to_head' => 3],
];

// Sort the teams based on tiebreaker criteria (e.g., head-to-head results)
usort($teams, function($a, $b) {
    if ($a['points'] == $b['points']) {
        if ($a['goal_difference'] == $b['goal_difference']) {
            if ($a['wins'] == $b['wins']) {
                return $b['head_to_head'] - $a['head_to_head'];
            }
            return $b['wins'] - $a['wins'];
        }
        return $b['goal_difference'] - $a['goal_difference'];
    }
    return $b['points'] - $a['points'];
});

// Print the sorted list of teams
foreach ($teams as $team) {
    echo $team['name'] . " - Points: " . $team['points'] . ", Goal Difference: " . $team['goal_difference'] . ", Wins: " . $team['wins'] . ", Losses: " . $team['losses'] . ", Head-to-Head: " . $team['head_to_head'] . "\n";
}
