What are some common mistakes to avoid when working with PHP to display rankings?

One common mistake to avoid when working with PHP to display rankings is not properly sorting the data before displaying it. To ensure accurate rankings, always sort the data based on the desired criteria before displaying it to the user. 

// Sample code to sort an array of rankings before displaying them

$rankings = array(
    "Player A" => 100,
    "Player B" => 80,
    "Player C" => 120,
    "Player D" => 90
);

arsort($rankings); // Sort the rankings in descending order

foreach ($rankings as $player => $score) {
    echo $player . ": " . $score . "<br>";
}
