I get that, but your initial comment implied you were about to showcase a counter to "Hundreds of lines just to grab a query parameter from a URL", but instead you showed "Poorly and incompletely parsing a single parameter can be done in less than 100 lines".
You said you allocated 5 minutes max to this snippet, well in php this would be 5 seconds and 1 line. And it would be a proper solution.
That would fail on a user supplying a multiple where you don't expect.
> If multiple fields are used (i.e. a variable that may contain several values) the value returned contains all these values concatenated together with a newline character as separator.
In GP’s defense, there is no standard behavior in the spec for handling repeated GET query parameters. Therefore any implementation-defined behavior is reasonable, including: keeping only the first, keeping only the last, keeping one at random, allowing access to all of them, concatenating them all with a separator, discarding the entire thing, etc.
