How can PHP developers efficiently guide users to relevant information within a forum interface, considering varying levels of technical expertise?

PHP developers can efficiently guide users to relevant information within a forum interface by implementing a search functionality that allows users to easily find topics or posts related to their queries. This can be achieved by using PHP to create a search bar that filters through forum content based on keywords and displays relevant results to the users. Additionally, developers can utilize categories and tags to organize forum content, making it easier for users to navigate and find information based on their level of technical expertise.

// PHP code snippet for implementing a search functionality in a forum interface

if(isset($_GET['search_query'])){
    $search_query = $_GET['search_query'];
    // Perform search query on forum content database
    // Display search results to the user
} else {
    // Display all forum content to the user
}
