While this is not necessary for gzip compliance (http://www.gzip.org/zlib/rfc-gzip.html#id-compliance) adding a function to read/write the mtime header when compressing or reading compressed files would be very useful in many cases. I currently use custom code to read/write the gzip mtime header. Read: $gzmtime = end(unpack('V', file_get_contents($gzfile, null, null, 4, 4))); Write: $r = fopen($gzfile, 'r+'); fseek($r, 4); fwrite($r, pack('V', $filemtime), 4); fclose($r); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=46577&edit=1
