uncompressing gz string

I don't understand why gzinflate and gzuncompress don't work?

<?php
$gz_content = file_get_contents('hello.txt.gz');

echo gzinflate($gz_content);
// Warning: data error

echo gzuncompress($gz_content);
// Warning: data error
?>

but if I make it from bash the content is there :
cat hello.txt.gz | gunzip
Hello!

I've had the exact same problem. I get .html.gz files uploaded to me. My
script does a file_get_contents on those, and then tried to use gzinflate or
gzuncompress. Neither works. Instead I use a shell command to use the 'gzip'
program to do the decompression.

This is a big bug that's been around a while, I'm surprised it hasn't been
fixed.

Regards, Adam.

i had a similar problem, it seems that a .gz file had 10 bytes of
header that inflate and uncompress didn't like, or something wierd
like that. but i can't find the code that i had in the end.

http://www.php.net/manual/en/function.gzinflate.php

but depending on how your actually using the data, one of the 'read
from the file' might serve you better

I dont see any open issues in bugs.php.net related to this.
