For the above example by VIJAY, using gzgetc would be better, as I've encountered binary/text file incompatibilities (at least with PHP 4.0.4).

<?
// this is simple code by VIJAY to unzip .gz file
$file = "/absolute/path/to/your/file" ;
$fp = fopen("$file", "w") ;
// file to be unzipped on your server
$filename = "filename.gz" ;
$zp = gzopen($filename, "r");
