What resources or documentation can be helpful for PHP developers looking to enhance search functionality in their projects?

To enhance search functionality in PHP projects, developers can utilize resources such as the official PHP documentation, online tutorials on implementing search algorithms, and frameworks like Laravel or Symfony that offer built-in search functionalities. Additionally, utilizing libraries like Elasticsearch or Apache Solr can greatly enhance search capabilities in PHP projects.

// Example PHP code snippet using Laravel's built-in search functionality
$results = App\Models\Post::where('title', 'like', '%'.$searchTerm.'%')
                           ->orWhere('content', 'like', '%'.$searchTerm.'%')
                           ->get();
