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).

<?php
// 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");

if (
$zp)
{
  while (!
gzeof($zp))
  {
    
$buff1 gzgets ($zp4096) ;
    
fputs($fp$buff1) ;
  }                
}            
gzclose($zp) ;
fclose($fp) ;
?>
