In my tests, Python can parse both Adler-32 and CRC32, while PHP can
only do Adler-32.
Anyways, I shortened my function:
function fixAdler32($data) {
static $f;
if (!isset($f)) $f = tempnam('/tmp', 'gz_fix');
file_put_contents($f, "\x1f\x8b\x08\x00\x00\x00\x00\x00" . $data);
return file_get_contents('compress.zlib://' . $f);
}
