Some gz string strip header and return inflated
It actualy processes some first member of the gz
See rfc1952 at http://www.faqs.org/rfcs/rfc1952.html for more details and improvment as gzdecode
<?
function gzBody($gzData){
if(substr($gzData,0,3)=="\x1f\x8b\x08"){
$i=10;
$flg=ord(substr($gzData,3,1));
if($flg>0){
if($flg&4){
list($xlen)=unpack('v',substr($gzData,$i,2));
$i=$i+2+$xlen;
}
if($flg&8) $i=strpos($gzData,"\0",$i)+1;
if($flg&16) $i=strpos($gzData,"\0",$i)+1;
if($flg&2) $i=$i+2;
}
return gzinflate(substr($gzData,$i,-8));
}
else return false;
}
?>

This can be used to inflate streams compressed by the Java class java.util.zip.Deflater but you must strip the first 2 bytes off it. ( much like the above comment )
$result = gzinflate(substr($compressedData, 2))
