POphp define class within class (or next best thing)

Body
copied!<p>I am aware that a class cannot be defined within a class in php, however I'm curious if there's another way to achieve the desired effect.</p> <p>I currently have a set of 3 objects used to conduct a search. The first is called $search_request. It contains properties like $keywords (string), $search_results_per_page (int), $page_requested (int), $owner_id (int)</p> <p>I also have an object called $search_result, it contains properties like $total_matches (int), $result_set (array of objects)</p> <p>Finally I have the $search_handler object which contains the $search_request and $search_result, along with functions that build the $search_result based on the $search_request. Usage goes like so:</p> <pre><code>$search_handler = new search_handler(); $search_handler->search_request->keywords = "cats, dogs"; $search_handler->search_request->search_results_per_page = 10; $search_handler->search_request->page_search_requested = 1; $search_handler->get_search_result(); echo $search_handler->search_result->total_matches; foreach($search_handler->search_result->result_set) { //do something } </code></pre> <p>All of this works fine. The problem is I want to repeat this model for different objects, so currently I'm forced to use the hackey solution of the "search_" prefix on each class.</p> <p>I'd like to have something like:</p> <pre><code>class search { public class request { $keywords = ""; $search_results_per_page = 5; $page_requested = 1; } public class result { $total_matches = null; $result_set = array(); } public get_results() { //check cache first $cached = look_in_cache(md5(serialize($this->request))); if($cached) { $this->result->result_set = $cached; $count = count($cached); $this->result->total_matches = $count; } else { //look in db $results = get_results_from_database($this->request->keywords); //db call goes here $this->result->result_set = $results; $count = count($results); $this->result->total_matches = $count; } } } //usage $search = new search(); $search->request->keywords = "cats, dogs"; $search->request->search_results_per_page = 10; $search->request->page_search_requested = 1; $search->get_results(); echo $search->results->total_matches; foreach($search->results->result_set as $result) { //do something } </code></pre>
