We design and implement a polymerization system for web learning resources based on CURL. Using the CURL multi-threading functions, the system can send data to all resource websites at the same time through GET or POST method. And then the system can unify all returned HTML codes from resources websites, and use regular expressions to extract the search results area of the returned codes. It uses PHP DOM manipulation class to fix the image and the URL addresses of links in the code, and then loads all returned code into the same page. Thus it can realize piecewise loading by using waterfall flow model.
