Related keyword query tool (PHP web version)

Related keyword query tool (HP web version) is a very rough query tool written in PHP. I made it when I was studying a year ago. I dug it out out of boredom to see that it still works. I would like to share it with everyone.

1. Fill in a word in the input box and click the "Query Related Words" button, and you will get many related keywords from Baidu search prompts, Baidu related searches, Baidu Index, Sogou prompts, Sogou related, etc., and the results are displayed one by one. in the frame.
2. "Baidu, Google, Soso", etc. at the top are used to switch search engines after clicking, which is an integrated search bar. Accordingly, you should click the "Search" button, regardless of related keywords.
3. In the related word query results section, you can click in each box on the left. Clicking on the result will enter the search results page, which of course corresponds to the search engine switched above.
4. The right side of the related word query results is a summary, which summarizes the related words found by each search engine. Click on the keyword to directly enter the search. The green button next to the keyword is used to continue to search for related words.
