How to decompress a gzip request PHP/Lumen/Laravel?

I am receiving requests from a third party that are gzip encoded text (~1mb so it makes sense)

My test route:

$router->post(
    'testgzip',
    function (\Illuminate\Http\Request $request) {
        $decompressed = null;
        if ($request->header('content-encoding') === 'gzip') {
            $decompressed = gzinflate($request->getContent());
        }

        return [
            'body' => $decompressed ?? $request->getContent(),
        ];
    }
);

My test file test.txt

hello world!

My sanity check:

curl --data-binary @test.txt -H "Content-Type: text/plain" -X POST http://localhost:8000/testgzip 
{"body":"hello world!"}

To compress it I run the command gzip test.txt

My curl:

curl --data-binary @test.txt.gz -H "Content-Type: text/plain" -H "Content-Encoding: gzip" -X POST http://localhost:8000/testgzip

Which triggers a

gzinflate(): data error

I also tried gzuncompress which triggers

gzuncompress(): data error

What am I doing wrong? How can I decompress a gzip request?

This one works for me

gzuncompress(base64_decode($request->getContent()));

For gzipped content you need to use gzdecode().

$decompressed = gzdecode($request->getContent());

This is built-in on PHP.

gzinflate() deals with deflated (not gzipped) and gzuncompress() with compresed (not gzipped) strings.
