How can PHP developers efficiently handle a large number of user entries in a database for a search and notification system?

When dealing with a large number of user entries in a database for a search and notification system, PHP developers can efficiently handle this by implementing pagination to limit the number of results displayed at once and using indexes on the database columns to improve search performance. Additionally, developers can optimize queries by using efficient SQL statements and caching frequently accessed data. 

// Example pagination code
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$limit = 10;
$offset = ($page - 1) * $limit;

$query = "SELECT * FROM users LIMIT $offset, $limit";
$result = mysqli_query($connection, $query);

while($row = mysqli_fetch_assoc($result)) {
    // Display user data
}
