Tedd, Thanks so much your thorough response - it's good to know that I'm not the only one trying to figure this out! I'm curious, in your code you use the PHP ftp functions, but I have used the PHP functions chmod() and mkdir() without establishing an ftp connection. Is it faster to establish an ftp connection within PHP and then use the ftp series of functions to accomplish all of the directory creation and permissions changes? If so, then I will probably change my code to follow yours. Andy On 9/25/06, tedd <tedd@xxxxxxxxxxxx> wrote:

Thanks for your response, Andy: I ran into the same problem trying to work with, and understand, permissions on a virtual host. When I asked this gang about permissions some time back, I received answers that ranged from RTFM to calling me stupid for using 0777, but none answered my question. No fault of the gang, I probably didn't ask the question correctly. In any event, I felt too stupid to ask the question again, so I went elsewhere looking for answers and eventually found something that works for me. Some consider me a novice, so I'll ask the gang to overview my comments to make sure that I'm not guiding you down the wrong path. As you know, the key to setting the permissions of a file depends upon the permissions the parent folder. If the parent folder permission is set to 0777, then we can change any files inside the folder as we want. However, that also presents a major security hole because then anyone can use that folder to upload and run evil code. So, the key problem is how to alter parent folder permissions. With virtual hosting, we can upload, manage, and set permissions as we want via our FTP connection software. So, I thought perhaps php had something like that and as such I discovered how to ftp connect via php. Now, not all php ftp_<commands> are available to php 4, but you can connect to your site and change permissions of folders, which is what we actually need. So, if you want to do something with a file: then change the folder permissions of the folder that holds it; do whatever you want with the file; and then change the folder permissions back to something safe. You can also create new folders if you want using the command ftp_mkdir(). Note, the beginning of the ftp_paths are different than url paths we would normally use to locate a file. For example: An example web path: http://www.yourdomain.com/rw/tmp/text.txt An example symbolic link: public_html/rw/tmp/text.txt The following code will show you an example of how this works. Just put in your own domain, user id, password, and correct paths and try it out. Change the permissions in the code and watch how the file permissions change. Please let me know if this works for you -- watch for line breaks. hth's tedd PS: I don't know what to say about your ".public_html/" directory, but I would just leave it alone. --- // how to call the function <?php $ftp_path = "public_html/rw/"; // note the ftp path $theDir = "tmp"; $theFile ="text.txt"; FtpPerms($ftp_path, $theDir, $theFile); ?> // the function <?php // create directory and change permissions via FTP connection function FtpPerms($path, $theDir, $theFile) { $server='ftp.yourdomain.com'; // ftp server $connection = ftp_connect($server); // connection $user = "you"; $pass = "yourpassword"; $result = ftp_login($connection, $user, $pass); // login to ftp server if ((!$connection) || (!$result)) { echo("No connection<br/>"); return false; exit(); } else { echo("Made connection<br/>"); ftp_chdir($connection, $path); // go to destination dir echo("Change permission<br/>"); $str="CHMOD 0755 " . $theDir; // change permissions for dir (note the space after 0775 ) ftp_site($connection, $str); echo("$str<br/>"); $filename = "$theDir/$theFile"; $contents = "This is the contents of the file."; echo("<hr><br/>Writing file <br/><br/>"); $file = fopen( $filename, "w" ); fwrite( $file, $contents); fclose( $file ); chmod($filename,0755); echo("Change permission<br/>"); $str="CHMOD 0600 " . $theDir; // change permissions back for dir ftp_site($connection, $str); echo("$str<br/>"); echo("Close connection<br/>"); ftp_close($connection); // close connection } } ?> -- ------- http://sperling.com http://ancientstones.com http://earthstones.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
