How can PHP developers optimize their code to handle cases where a search term appears in multiple database entries?

When a search term appears in multiple database entries, PHP developers can optimize their code by using pagination to limit the number of results displayed per page. This can prevent overwhelming the user with too much information at once and improve the performance of the search functionality. Additionally, developers can implement caching mechanisms to store and retrieve search results efficiently. 

// Example PHP code snippet implementing pagination for search results

// Set the number of results to display per page
$results_per_page = 10;

// Calculate the total number of pages based on the total number of search results
$total_results = count($search_results);
$total_pages = ceil($total_results / $results_per_page);

// Determine the current page number from the URL parameter
$current_page = isset($_GET['page']) ? $_GET['page'] : 1;

// Calculate the starting index for the current page
$start_index = ($current_page - 1) * $results_per_page;

// Display search results for the current page
for ($i = $start_index; $i < min($start_index + $results_per_page, $total_results); $i++) {
    echo $search_results[$i];
}

// Display pagination links
for ($page = 1; $page <= $total_pages; $page++) {
    echo "<a href='search.php?page=$page'>$page</a> ";
}
