A Query String Parser Guide
The query string is the part of a URL after the question mark. Its rules are simple but easy to get wrong by hand.
Keys, values and separators
Parameters are key=value pairs joined by ampersands. A parser splits on those separators and decodes each part, so you read the intended values rather than the raw encoding.
Repeated keys
The same key can appear more than once, which some frameworks treat as an array. A parser that lists every occurrence makes this behaviour visible instead of hiding duplicates.
Frequently asked questions
Can I use this for production work?
Yes, for inspection, formatting and quick generation. Still review the output before committing it to production code or configuration.
