How can PHP developers handle gaps in ID sequences when implementing navigation features?

When implementing navigation features in PHP, developers can handle gaps in ID sequences by using a loop to iterate through the IDs and check for missing ones. If a gap is found, the navigation can adjust accordingly by skipping over the missing ID. 

// Example PHP code snippet to handle gaps in ID sequences in navigation

$ids = [1, 2, 4, 5, 7]; // Example array of IDs
$previous_id = null;

foreach ($ids as $id) {
    if ($previous_id !== null && $id - $previous_id > 1) {
        // Handle the gap in ID sequence
        echo "Gap found between ID " . ($previous_id + 1) . " and " . ($id - 1) . "<br>";
    }

    // Display navigation link for current ID
    echo "<a href='page.php?id=$id'>Page $id</a><br>";

    $previous_id = $id;
}
