This is because the checked query string format is inconsistent, and the RFC standard does not specify what format the query string should be, so the various languages have their own format for one-key multivalued, such as jquery (or JS series): rzqd=网络搜索&rzqd=自己 or rzqd=网络搜索,自己, but the format of PHP is rzqd[]=网络搜索&rzqd[]=自己 . I think you either directly on the form, or you write a function to parse it, it is not complicated anyway.
