Question

I can’t find the answer I need, so I hope you understand what I’m after.

I need to be able to open a tar.gz file (from a remote website), read the files, and copy/replace these files on my website. I’ve been trying this code (as well as countless other codes):

$zipFile= 'http://awebsite.com/file.tar.gz';
$dir = 'myfolder';
$zp = @gzopen($zipFile, "r");
$fp = @fopen($dir, "w");
while(!@gzeof($zp)) {$string = @gzread($zp, 4096); @fwrite($fp, $string, strlen($string));}
@gzclose($zp);
@fclose($fp);

All seem to come up with errors of different sorts. I seem to be able to read the zip file, but not actually save the contents to my website.

Thanks for any help in advance.

Try this:

<?php
$zipFile= 'http://awebsite.com/file.tar.gz';
$dir = 'myfolder';
$zp = @gzopen($zipFile, "r");
$fp = @fopen("temp.tar", "w");
while(!@gzeof($zp)) {$string = @gzread($zp, 4096); @fwrite($fp, $string, strlen($string));}
@gzclose($zp);
@fclose($fp);
exec('tar xf temp.tar --overwrite --directory='.$dir);
?>

Update:

Here is a solution without using a temporary file and tar handles the gzip decompression itself:

<?php
$zipFile= 'http://awebsite.com/file.tar.gz';
$dir = 'myfolder';
$zp = @fopen($zipFile, "r");
$fp=popen('tar xzf - --overwrite --directory='.$dir,'w');
while(!@feof($zp)) {$string = @fread($zp, 4096); @fwrite($fp, $string, strlen($string));}
@fclose($zp);
@fclose($fp);
?>
