Digg  chown
Changes file owner
(PHP 4, PHP 5)
Code Examples / Notes » chowntayfun bilsel
Simple usage of the chown: <?php $file_name= "test"; $path = "/var/www/html/test/" . $file_name ; $user_name = "root"; chown($path, $user_name); ?> klaus zierer
If you want to chown a symlink, PHP will follow the symlink and change the target file. If you want to chown the symlink, you have to use shell_exec("/bin/chown user.group symlink"); njs+php
If you allow sudo execution for chmod by "nobody" (www, webdaemon, httpd, whatever user php is running under)in this manner, it had better be a system on which the owner is able to be root and no one else can run code, else your whole system is compromised. Someone could change the mode of /etc/passwd or the shadow password file. Other system commands (sudo mount) and so forth are similar. martijn
If chown is filled with a variable ( chown ("myfile", $uid) the uid will be looked up through pwget_uid. So if you need to set a non existing uid use inval($uid). jens vieler
for some reason i was searching for chown() with an "on this mashine"-unknown userid and found martijn's hint very interesting. the main problem is, that if the numerical uid is used within a variable, it is checked against the /etc/passwd and returns "unknown user". a little note: use intval(), not inval()! so all in all it is: chown($path_to_dir,intval($uidnumber)); richard esplin
As far as I can tell, PHP's built in functions will not do a recursive chown or chgrp. But it wouldn't be hard to write a function for this. Here is some starter code based on an example written by John Coggeshall which I found at http://www.coggeshall.org : <?php function recurse_chown_chgrp($path2dir, $uid, $gid){ $dir = new dir($path2dir); while(($file = $dir->read()) !== false) { if(is_dir($dir->path.$file)) { recurse_chown_chgrp($dir->path.$file, $uid, $gid); } else { chown($file, $uid); chgrp($file, $gid); } } $dir->close(); } ?> I have not tested this code (but I think it will work) because for my current needs, a simple exec("chown -r $user.$group $path"); is sufficient. I would need this code if I were not in control of the contents of these variables because they can be dangerous on the command line. greg _at_ rhythmicdesign d.o.t com
<?php function recurse_chown_chgrp($mypath, $uid, $gid) { $d = opendir ($mypath) ; while(($file = readdir($d)) !== false) { if ($file != "." && $file != "..") { $typepath = $mypath . "/" . $file ; //print $typepath. " : " . filetype ($typepath). " " ; if (filetype ($typepath) == 'dir') { recurse_chown_chgrp ($typepath, $uid, $gid); } chown($typepath, $uid); chgrp($typepath, $gid); } } } recurse_chown_chgrp ("uploads", "unsider", "unsider") ; ?> for older versions.. unfortunately, it seems I do not have permission to perform these functions. |
