How can PHP be used to display different messages based on a specific range of points?

To display different messages based on a specific range of points in PHP, you can use conditional statements such as if-else or switch-case. You can check the value of the points and display different messages accordingly. For example, if points are between 0-50, display "Poor performance", if points are between 51-75, display "Average performance", and if points are above 75, display "Excellent performance".

$points = 80;

if ($points >= 0 && $points <= 50) {
    echo "Poor performance";
} elseif ($points > 50 && $points <= 75) {
    echo "Average performance";
} elseif ($points > 75) {
    echo "Excellent performance";
}
