💡 Key Code Examples

Secure Password Validation

// Password validation with multiple requirements
$hasNumber = preg_match('/[0-9]/', $UserPass);
$hasLower = preg_match('/[a-z]/', $UserPass);
$hasUpper = preg_match('/[A-Z]/', $UserPass);
$hasSpecial = preg_match('/[!@#$%^&*()_+{}[\]<>?]/', $UserPass);

if (!$hasNumber || !$hasLower || !$hasUpper || !$hasSpecial) {
    header("Location: register.php?error=3");
    exit();
}

Session Management

if (session_status() === PHP_SESSION_NONE) {
    session_start();
}

// Protected route check
if (!isset($_SESSION['username'])) {
    header("Location: ../auth/login.php");
    exit();
}

Marks Calculation

// Calculate statistics
$total = array_sum($marks);
$average = $total / count($marks);
$highest = max($marks);
$lowest = min($marks);

// Grade calculation
if ($average >= 85) $grade = 'HD';
elseif ($average >= 75) $grade = 'D';
elseif ($average >= 65) $grade = 'C';
elseif ($average >= 50) $grade = 'P';
else $grade = 'F';
