Re: [RFC] [Discussion] Query Parameter Manipulation Support

Hi Tim, First of all, thanks for your detailed explanation! Does that make sense? > Sure, this is a very sensible approach, similar to the algorithms I have also considered myself before. The reason why I started to search for alternatives is because lookups are inefficient this way: all get*() methods have an O(n) time complexity by default, while currently, looking up keys in $_GET is O(1). This regression is what I tried to avoid with storing query params along with an array key. However, I realized in the meanwhile that it may be possible to eliminate much of the performance overhead by using two hash tables: one for exact search (WHATWG URL-alike API), and one for searching the prefixes before the [] pair (for the array API). I haven't tried this idea out yet in practice, so I'll need to do some POC first before continuing with the RFC. Regards, Máté
