A crawler is the bot that crawls a site to rank it and or submit it into a search engine. A directory search engine is a website that has websites listed on it and allows you to search for what you are looking for inside of the directory.
The oldest major directory on the web is Yahoo! Directory, which was launched in 1994 by Jerry Yang and David Filo. It started as a simple list of websites organized by categories and quickly grew into a comprehensive directory that helped users navigate the burgeoning internet. Yahoo! Directory played a significant role in the early days of the web, although it was eventually discontinued in 2014 as search engines evolved.
Yahoo became a proper search engine in 2004 A.D.

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.
