A search engine is a database of websites. Each search engine has a dedicated spider that regularly crawls the net. Search results are displayed according to the keywords entered by Internet users. A directory is catalogue of websites classified by categories. Unlike search engines, submitted websites are reviewed by a human editor.
You can check if a directory exists using the file_exists() function. file_exists(\'http://www.example.com/path/to/directory/\'); It returns boolean TRUE if the directory exists; boolean FALSE otherwise. Incorporting this function with a searching algorithym will make a successful directory search engine. Alternatively, you can make the engine very simple, and check if the exact directory name exists.
