How was Haitou.com developed?

The picture comes from the technical support at the bottom of Haitou.com. This should be developed by Huake. It is based on PHP and specializes in grabbing information from various university recruitment websites. The page should be a pseudo-static page generated by PHP. Please tell me how to control the frequency of updates. Is it an automatic update or a manual update? Can PHP automatically crawl pages and generate pseudo-static pages? How to implement this website? What are the technical difficulties in implementation?

There is nothing that PHP cannot do in web development. At most, it is suitable or not suitable. I feel a little excited that someone is paying attention. . . It is based on PHP, and the update frequency is of course enough to satisfy you so that you will not miss the seminar.
Whether it is automatic or manual, it will definitely be updated automatically in your opinion, and you will never be asked to manually update today’s information. All right. . . It seems that the question is not answered, but I am not Gree in the team, I can master the core technology, and I can’t answer it, so if you want to know more, you are welcome to join us~
As for the interface problem that many people complain about, that, in fact, we At first, I didn’t want to do a commercial project at all. I was just too lazy to look around and thought it would be refreshing to find a place to gather information from the seminar. Then you start to collect everywhere, and when you collect, people start to defend you, which arouses your desire to break defense, and then you can't stop playing siege games one by one. Then as you collect and collect, you find that the number of clicks slowly increases, and so on. I found that many people actually wanted to watch it together like this. . . Then I realized that it was a bit inappropriate to show others the paper we used before. . .
So the gorgeous, fresh and new interface will appear soon, and the refreshing feeling of eating big chunks of meat and watching blockbusters of information is still~, many immatures are slowly changing, The world is often unkind to new talent, new creations. The new needs friends. Born in school, I just hope to understand you better than outside the school. I hope everyone will continue to support you ~ Information conference inquiry system I know this. Their team has more than 50 people and they update it manually. The so-called "automatic" and "frequency" mainly depend on business needs.

I haven’t paid attention to the system you mentioned, but as long as the crawl source is defined, there are many ways to execute PHP scripts regularly. The most commonly used one is the system’s scheduled tasks. After all, PHP writes background resident processes. The functional risk is still relatively high.

I think the application itself here has relatively high requirements for data validity. I think the frequency should be relatively high, which depends on the server hardware and network. Let me give you a correct answer.
The first one is automatic, which contains a lot of information. Manual processing will screen out some that do not meet the quality, or do not meet the radiation range of Haitou.
Just the sauce.
Don’t ask me why I know. It is automatically captured. I am responsible for the employment information network of Wuhan University of Technology. I added the code on it and they did not generate the original site mode. Moreover, they will often adjust the capture method. The monitoring of the system should be very good.
