Description

Description

The following code:

<?php
$data="test";
var_dump(gzuncompress(gzcompress($data,1, ZLIB_ENCODING_DEFLATE)));
var_dump(gzuncompress(gzcompress($data,1,ZLIB_ENCODING_RAW)));

Resulted in this output:

string(4) "test"

Warning: gzuncompress(): data error in /in/Ms5o8 on line 4
bool(false)

But I expected this output instead:

string(4) "test"
string(4) "test"
