Come scompattare un .gz

Con la libreria Zlib inclusa in PHP, una volta aperto il file con gzopen, come faccio a scompattarlo sul server?

grazie

Codice PHP:


$filename = "upload/7_file.tar.gz";

print "<html>\n<head></head>\n<body>\n<pre>\n";

$s = "Only a test, test, test, test, test, test, test, test!\n";



// open file for reading

$zp = gzopen($filename, "r");

$compressed = gzread($zp,1000);



$uncompressed = gzuncompress($compressed);

echo $uncompressed;





print "\n";



print "</pre>\n</h1></body>\n</html>\n";

Risultato:
Warning: gzuncompress: data error in e:\programmi\apache group\apache\websites\dalla\sito\zip.php on line 11

ciao, ho provato il seguente codice e funziona:

codice:

//COMPRESSIONE DEL FILE
$filename = "phpinfo.php";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);
$compressed = gzcompress($contents, 9);
$filename = "phpinfo.gz";
$handle = fopen($filename, "w");
$contents = fwrite($handle,$compressed);
fclose($handle);

//DECOMPRESSIONE DEL FILE
$filename = "phpinfo.gz";
$zd = gzopen($filename, "r");
$compressed = gzread($zd, 10000);
gzclose($zd);
$uncompressed = gzuncompress($compressed);
$filename = "phpinfo-2.php";
$handle = fopen($filename, "w");
$contents = fwrite($handle,$uncompressed);
fclose($handle);
