How can PHP loops be effectively used to ensure that each team plays against every other team exactly once?

To ensure that each team plays against every other team exactly once, we can use nested loops to iterate through each combination of teams and generate the match-ups. By keeping track of the teams that have already played against each other, we can avoid duplicate match-ups. 

$teams = ['Team A', 'Team B', 'Team C', 'Team D'];

for ($i = 0; $i < count($teams); $i++) {
    for ($j = $i + 1; $j < count($teams); $j++) {
        echo $teams[$i] . ' vs ' . $teams[$j] . '<br>';
    }
}
