So, like, do they download it later, or is your PHP program supposed to return the compressed archive?... Let's assume the latter, cuz that's more fun :-) Use a URL like this: http://yourserver.com/whatever.php/whatever.tgz Your PHP file is whatever.php That bogus-looking whatever.tgz on the end is because [BLEEP]ing IE 3.mumble ignores MIME-Type and goes by the URL ending to decide what kind of file you are returning. MS sucks. Or is it Netscape that does that? Netscape sucks too. <?php $path = "/path/you/want/to/compress/*"; exec("tar -cz $path", $results, $errorcode); if ($errorcode){ echo "<HTML><BODY>\n"; echo "OS Error: $errorcode. Usually path/permissions. Use 'man errno' to look up this number if it makes you feel good.<BR>\n"; # Hmmmmmm. You might need a " 2S|" or similar after the $path above # to get stderr to redirect to stdout so PHP can get error messages from tar... # Any gurus want to comment on how that works, and if " 2S| " is the right mojo? # I hate Un*x some days. :-) echo "Here's what tar had to say, if anything:<BR>\n"; while (list(,$line) = each($results)){ echo $line, "<BR>\n"; } } else{ header("Content-type: application/octet-stream"); # Force download header("Content-disposition: filename=whatever.tgz"); # Is strlen() binary safe?... If not, this next line will mess you up... # But without it, the browser can't do that nifty progress meter during download. header("Content-length: " . strlen($results)); # There's probably more headers you want... echo $results; } ?> >I know I should test these, but sending a message is easier. :) >If a connect the server using ftp_connect and ftp_login, when I try to create a directory >using mkdir or ftp_mkdir or a file using fopen, will they belong to me or to nobody??? They will belong to whomever you connected to the FTP server as, assuming that user can even create files in the first place... mkdir() and fopen() in your local server will belong to whomever PHP (Apache) runs as, which is usually "nobody", but could have been configred in httpd.conf to be "www" or any valid user, including "root" if you were incredibly stupid, or, if you run PHP as a CGI and wrap it in suExec, it would be whatever user suExec is configured to run PHP as, which might be your real login, or might not. Didja follow all that? :-) http://php.net/chown et al may or may not be of use... -- WARNING richard@zend.com address is an endangered species -- Use ceo@l-i-e.com Wanna help me out? Like Music?
