PHP - File Permission Problem
Hello
I built a component for a non-profit organisation which want to use the 404page to promote several charities. In order to do that I want to place a file 'error.php' in the map 'templates/system'. I use the RENAME function for that. So far so good. On many sites it works fine, but on other sites I get an error on the rename function. The user-id and the group-id of the script I use are the same as the uid's of 'templates/system'. So there shouldn't be a problem. If I add public write to the filepermissions of 'templates/system'/ with Filezilla the error disappears. But I can't do that with the php chmod function, again because of too less priviliges. HELP, I can't find an explanation for that and that's driving me crazy. thanks in advance Similar TutorialsI have a PHP web system that store in a windows server. In the system, there is a function for user to upload files to another server (Shared server in Unix). When i try to upload a file, it gives warning: Warning: move_uploaded_file(\\unixserver/sharedfolder/upload/test.txt) [function.move-uploaded-file]: failed to open stream: Permission denied in C:\wamp\www\upload\index.php on line 40 For your information, my username has been assigned in xxx's group that has access to read and write on that folder. Besides, i'm able to open,create and delete files on that folder's server manually (samba). The safe mode setting is off. Does anybody has any idea why this thing happen? I am using apache web server on linux. I am using PHP for web designing. On web server, i want to show the configuration data by reading the ini file. I am creating this ini file from one php code itself. If this php code i run through linux terminal, the file is created with file and group owner as root.(i am having sudo rights on machine) Then if i try to read the ini file from my apache web server, it gives warning as failed to open stream: permission denied. I have tried changing the owner, and permissions to 777 of the file. Still it is not readable.
On the other hand, if i run the php code of ini file creation through web server, ini file is created with file and group owner as apche. and web server is able to read/ write the file.
But i want to create that file from root or some other user and later read/written by apache.
How to give this access permission?
Maybe never mind. Just noticed ssphpd doesn't have a group... ps. do I have the umask part right? Edit 2. No, it didn't help... I have two users (ssphpd and apache) which will need to write files to a given directory and its subdirectories. My intent was to set them up with ssphd's group and use the setgid to make all future files and directories inherit that group. Not sure, but I don't think I have this right yet as I indicate at the end of this post. [michael@bb5 ~]$ sudo useradd -r ssphpd [michael@bb5 ~]$ sudo usermod -aG wheel ssphpd [michael@bb5 ~]$ sudo usermod -aG wireshark ssphpd [michael@bb5 ~]$ sudo usermod -aG ssphpd apache [michael@bb5 ~]$ groups apache apache : apache ssphpd [michael@bb5 ~]$ groups ssphpd ssphpd : ssphpd wheel wireshark [michael@bb5 ~]$ [michael@bb5 ~]$ sudo chmod g+rwx -R /var/www/~/storage [michael@bb5 ~]$ sudo chown michael.ssphpd -R /var/www/~/storage [michael@bb5 ~]$ sudo chmod g+s /var/www/~/storage My script to write this files is below:
public function setFile(array $file, string $nameAlias):void {
$path=$this->getPath($nameAlias, true);
$this->moveTo($file['tmp_name'], $path);
}
private function getPath(string $name, bool $create):string {
//$name is 20 characters
$p1=$this->uploadDirectory.'/'.substr($name,0,2);
$p2=$p1.'/'.substr($name,2,3);
$p3=$p2.'/'.substr($name,5,4);
$old_umask = umask(0);
if($create) {
if(!file_exists($p1)){mkdir($p1, 0775);}
if(!file_exists($p2)){mkdir($p2, 0775);}
if(!file_exists($p3)){mkdir($p3, 0775);}
}
umask($old_umask);
return $p3.'/'.substr($name,9);
}
private function moveTo(string $tmpname, string $path):void {
syslog(LOG_ERR, "attempting to move $tmpname to $path");
$uid = posix_getuid();
syslog(LOG_ERR, "user PHP is running as: $uid - ".posix_getpwuid($uid)['name']);
$gid = posix_getgid();
syslog(LOG_ERR, "group PHP is running as: $gid - ".posix_getpwuid($gid)['name']);
$this->test($tmpname);
$this->test(substr($path,0,-12));
syslog(LOG_ERR, move_uploaded_file($tmpname, $path)?'success':'failure');
}
private function test(string $file):void {
syslog(LOG_ERR, "$file is writable: ".(is_writable($file)?'yes':'no'));
$uid=fileowner($file);
syslog(LOG_ERR, "$file owner: $uid - ".posix_getpwuid($uid)['name']);
$gid=filegroup($file);
syslog(LOG_ERR, "$file group: $gid - ".posix_getpwuid($gid)['name']);
$perms=fileperms($file);
syslog(LOG_ERR, "$file permissions: $perms - ".$this->formatPerms($perms));
}
However, as seen, not only can only apache write files, the newly created directories are displaying apache's group instead of ssphp's group. Any ideas?

(WAMP using Win XP). Once I select the file and click submit I get the error: "Forbidden... You don't have permission to access /< on this server." with URL http://localhost/<?=$PHP_SELF?> Code is below: <form action="<?=$PHP_SELF?>" method="post" enctype="multipart/form-data"> <br/><br/> Choose a file to upload:<br/> <input type="file" name="upload_file"> <br/> <input type="submit" name="submit" value="submit"> </form> TIA Im in the process of setting up a social media site , Just switched from basic hosting to Dedicated Server Everything was working till i switched . I have a basic join forum and email activation , On the register.php file it tell script to make a directory mkdir into member/folder like this below, But it will make the folder for the id of that user but will not let them upload any images?. At first it wouldnt even make a folder but i found out it was a permissions issue with my server i fixed it , im guessing the upload is also a permission's issue ? But the script automaticly make the members/"$id" folder and i dont know how to set permission for auto create folder that if i even have to ? so confused. (BEGGGGINGG !!

How can I ftp this file? What is going on? Thanks, Chris So i am on a shared host and it seems that only 777 allows me to upload images on a certain folder , not 755 , just 777... is it because of the shared host or thats how it works? PS: i really didnt know where to post it so if a mod can move it , i'd appreciate it. Hi. I'm using SimpleImage.php to do some basic image manipulation. The code is here http://www.white-hat-web-design.co.uk/articles/php-image-resizing.php, but I don't think all the details are important. Basically, I'm trying to read and image and save it with a different name. I'm really new with this stuff, so it's probably something simple. Anyway, here is the code throwing the error, $image_info = getimagesize($filename); where $filename is a string containing the path to the image I want to load, e.g. $filename="images/picture.jpg"; It's throwing a "Read Error!" I know that the path is correct. In fact I first check if the file is there using is_file($filename); and it returns true. I'm guessing that maybe php does not have "permission" to read this file. The permissions for the file are -rw-r--r-- 1 www-data www-data 80211 2011-04-20 16:19 picture.jpg Looks like everyone has "read" permission, so I don't see what the problem is. Also, the permissions of the folder and all parent folders are 777. Not sure what the problem is. I might be way off by guessing that it is a permissions problem. Any help would be great. Thanks. Also, I was wondering if there is a way for this forum to email me whenever there is a reply to my posts. I can't seem to find the option anywhere. I have use apache server with PHP installed on it,i created one directory through php coding it get created but it has permission ( drwxr-sr-x 3 www-data www-data 4096 Feb 26 04:54 Merchantid_30) my other directories has ubuntu:ubuntu permission, I want to write on my directory but www-data wont allow me to write on it,giving 777 permission through chmod is risky, can i create directory through php but its default permission is set to be ubuntu:ubuntu instead of www-data ? what changes i need to do in coding?
PHP is owner of image directory with "permissions 660." My script is: $imagePath = '../imageDirectory/'.gif'; $image = imagecreatefromstring(base64_decode($raw_image_data)); $rotate = imagerotate($image,-90,0); imagegif($rotate,'../imageDirectory/'.gif'); Is it because the imagerotate and imagegif functions need the execute requirements to be able to monkey with the image? Thank you.
Sub question (maybe more important than the first question): Thank you. Hi. I'm trying to make my folder management tool able to remove stuff. Problem is, I get permission denied.
I've checked the NFTS perms for the share and for the folder. It's also not read only. I logged into my other workstation as the service account the web server is using and opened a DOS window and did "rd \\server\share\folder" and it removed it no problem. It just fails in PHP. Any idea what I should be looking at? Thanks!
Edited by Strahan, 02 August 2014 - 05:06 PM. i want that when someone post some comment on post that don't insert in table directly before inserting i can check and after approving then insert in table for which what i doo ?any IDea about this i have some questions on how folders and files permissions work. say i have users directories outside 'protected' as below.. Code: [Select] users -- usera -- docs -- userb -- docs protected i do not want user B who does not have the rights, to access anything in user A directories. also, i do not want any person to access the directories directory via url links. basically i just want users to be able to access their own directories, and no one else. how can it be done? thanks! I want to delete an image file from a folder using unlink. The code is : Code: [Select] $movie_id = $checkbox[$i]; $sql = "DELETE from movie_basic_details where `movie_id` = '$movie_id'"; $result = mysql_query($sql) or die(mysql_error()); $sql1 = "DELETE from movie_details where `movie_id` = '$movie_id'"; $result = mysql_query($sql1) or die(mysql_error()); $sql2 = "DELETE from movie_stars where `movie_id` = '$movie_id'"; $result = mysql_query($sql2) or die(mysql_error()); $query = "select movie_name from movie_basic_details where movie_id = '$movie_id'"; $res = mysql_query($query) or die(mysql_error()); $data = mysql_fetch_array($res); unlink("upload/movies/".$data['movie_name']); } The entries in the database have been deleted but only the image corresponds to that entry do not get deleted. The following warning comes up : Warning: unlink(upload/movies/) [function.unlink]: Permission denied in C:\wamp\www\ContentPanel\deletemovies.php on line 23 I have uploaded the files using $_FILES server variable and move_uploaded_file function. I am running this script on windows 7. Please Help. Hmm, hello everyone, i'm running my php in an ubuntu server and I'm trying to run a command using exec (i.e. 'echo 1 > /var/www/test.txt') but I always get a permission denied issue, although i've already changed the permissions to 777 (read-write-execute) Any solution? I have started a project using laravel. I am in the process of builing User groups and permissions in the admin dashboard.

Hi I have an image uploading script that won't upload images... It worked at one point when i had folder permission at 0777 but i was told that is risky so i changed it to 0775 Now it won't work and i can't use 0777. Any one know what i need to do to get it to work? This is my script: Code: [Select] <?php $salt = 35322232414; $name = $salt.$safe; $name = md5($name); if(isset($_POST['submit'])){ if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/png") || ($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < 1000000)) { if ($_FILES["file"]["error"] > 0) { echo $_FILES["file"]["error"]; } else { $filename = md5(serverdate()) . $_FILES["file"]["name"]; if (file_exists("userimages/".$name."/".$filename)) { echo "Image already uploaded!"; } else { if (is_dir("userimages/".$name) == FALSE){ mkdir("userimages/".$name, 0775); //permissions } move_uploaded_file($_FILES["file"]["tmp_name"], "userimages/".$name."/" . $filename); echo "Image has been uploaded!"; } Error i get: Quote Warning: move_uploaded_file(images/73640de25b7d656733ce2f808a330f18/7fc9cb9cf5ae1f7a5dd9105d3f9559fb_63.jpg) [function.move-uploaded-file]: failed to open stream: Permission denied in uploadfile.php on line 41 Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/tmp/phpjrX3SO' to 'images/73640de25b7d656733ce2f808a330f18/7fc9cb9cf5ae1f7a5dd9105d3f9559fb_63.jpg' in uploadfile.php on line 4 Hi, On login page load, (even before submitting user name and pass) Debugger finds "permission denied error", can see it he goldpharm.co.il/authentication.php Now, when a user submit's user name and pass, nothing happens, it stays on the login page.
