length: The length of data to get.

返回值

The uncompressed string, or FALSE on error.

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");



if ($zp)

{

  while (!gzeof($zp))

  {

    $buff1 = gzgets ($zp, 4096) ;

    fputs($fp, $buff1) ;
