Make a copy of a File with PHP or JavaScript - php

How can I make a copy of a file on my server from a site either in PHP or JavaScript?
I tried the following:
<?php
$file = 'example.txt';
$newfile = 'example.txt.bak';
if (!copy($file, $newfile)) {
echo "failed to copy $file...\n";
}
?>
But I keep getting the "failed to copy" message
I created a copy.php file in my var/www/html folder (Using Apache in Ubuntu) and I ran the copy.php file in my browser http://localhost/copy.php
My example.txt is sitting right in the same folder that copy.php
Thanks

You need to set destination folder permissions to 646. Use your domain cpanel or equivalent to do that

In ubuntu you would need to set your folder permissions so navigate to your project directory using cd in the command prompt 'cd /var/www/html/myproject'
var/www/html/myproject
Lets say the folder your want to copy to is located at
var/www/html/myproject/copied_files
now run the command 'sudo chown -R <your username on ubuntu>:www-data <folder name>
It should look like this
Lets say my user name is prince
prince#computer: var/www/html/myproject $ sudo chown -R prince:www-data copied_files
Essentially your giving the group "www-data" which is your server permission to write files to that directory while you still have ownership to it. The '-R' says that all subfolders should be writable by 'www-data' (your server) so you don't have to manually make it writeable and the 'copied_files' is the name of directory for your server to write too :)

Error in phpMyAdmin after updating to v4.8.0: The $cfg['TempDir'] (./tmp/) is not accessible

phpMyAdmin worked fine with v4.7.9. Now after updating to v4.8.0 today (replacing the old phpmyadmin folder against the new one) I'm getting this message in phpMyAdmin:
The $cfg['TempDir'] (./tmp/) is not accessible. phpMyAdmin is not able
to cache templates and will be slow because of this.
I added the folder ./tmp/ like like this: /usr/share/tmp
phpMyAdmin is on: /usr/share/phpmyadmin
This didn't change anything.
Who know this error? What can I do?
Solution was to create a folder called tmp like this: /usr/share/phpmyadmin/tmp.
Also make sure that the user (or group) running the webserver (e.g. Apache) has write access to the newly created tmp folder. Consequently, change the ownership to that user or add write access for all users. The latter one might not be really advisable.
simple fix is to create tmp dir in your phpmyadmin dir and set permission to 777
mkdir tmp && chmod 777 tmp
then
update your config.inc.php file add that line
$cfg['TempDir'] = 'tmp';
I had this same problem on Ubuntu 18.04 when I replaced the phpMyAdmin version from the package repository (v4.6.6) with the latest version (4.8.0). I don't know if you are running on Ubuntu, but maybe my response will be helpful to you (or others) who encounter something similar.
I put the new version in the standard location, /usr/share/phpmyadmin/, but Ubuntu's package installation of PMA puts some configuration settings in other places (see /etc/phpmyadmin/ and /var/lib/phpmyadmin/). I found this setting in /etc/phpmyadmin/apache.conf:
php_admin_value upload_tmp_dir /var/lib/phpmyadmin/tmp
and sure enough that directory had been created and had the proper permissions. Wanting to stay as close as possible to the package installation settings, I made this change in /usr/share/phpmyadmin/libraries/vendor_config.php and pointed directly to that folder:
//define('TEMP_DIR', './tmp/');
define('TEMP_DIR', '/var/lib/phpmyadmin/tmp/');
This setting is picked up by /usr/share/phpmyadmin/libraries/config.default.php (which you are not supposed to edit) to set $cfg['TempDir'].
In my case I added
$cfg['TempDir'] = '/usr/share/phpmyadmin/temp';
to the
config.inc.php
File within the phpmyadmin folder
Hope it will help someone
Create a temp directory owned by and restricted to the webserver user. Do not place it inside of the phpMyAdmin webroot. (In this example, the webserver runs as apache):
mkdir -p /var/tmp/phpMyAdmin
chown apache:apache /var/tmp/phpMyAdmin
chmod 700 /var/tmp/phpMyAdmin
Next, set TempDir inside of phpMyAdmin's config.inc.php:
$cfg['TempDir'] = '/var/tmp/phpMyAdmin';
Any answer suggesting that you create /usr/share/phpmyadmin/tmp is advocating bad security practice. This is generally true for temp directories, and explicitly stated in the official phpMyAdmin documentation:
For security reasons, all directories should be outside the tree
published by webserver.
For me phpmyadmin dir was found inside /opt/lampp/
open teminal inside /opt/lampp/phpmyadmin/
give root privileges to the terminal by typing sudo su command.
now in same terminal use (mkdir -p /tmp/) hit enter
now, chmod 777 /tmp
Inside phpmyadmin directory there is a file config.inc.php. Open it using same terminal .
add this line $cfg['TempDir'] = /tmp; and Save.
Now you are good to go , just reload the tab and the error will be gone.
Create a tmp folder in the base directory of the phpMyAdmin install (e.g. /usr/share/phpmyadmin/tmp), and make sure that it is writable by the user that PHP is running under.
From the phpMyAdmin documentation:
$cfg['TempDir']
Type: string
Default value: './tmp/'
The name of the directory where temporary files can be stored.
It is used for several purposes, currently:
The templates cache which speeds up page loading.
ESRI Shapefiles import, see 6.30 Import: How can I import ESRI Shapefiles?.
To work around limitations of open_basedir for uploaded files, see 1.11 I get an ‘open_basedir restriction’ while uploading a file from the import tab..
This directory should have as strict permissions as possible as the only user required to access this directory is the one who runs the webserver. If you have root privileges, simply make this user owner of this directory and make it accessible only by it:
chown www-data:www-data tmp
chmod 700 tmp
If you cannot change owner of the directory, you can achieve a similar setup using ACL:
chmod 700 tmp
setfacl -m "g:www-data:rwx" tmp
setfacl -d -m "g:www-data:rwx" tmp
If neither of above works for you, you can still make the directory chmod 777, but it might impose risk of other users on system reading and writing data in this directory.
well,in my case this error has occured when i was using ubuntu 18.04.
All you need is to go to the installation directory (in ubuntu - opt/lampp/phpmyadmin)
and create a folder tmp with all the suitable read/write permissions.
Follow these steps in case of ubuntu-
1.go to the PMA installation directory by typing following commands in cmd-
cd opt/lampp/phpmyadmin
2.Then type the following command-
sudo mkdir tmp && chmod 777 tmp
and then you are done..!!
I hope it helps..
1) create the tmp folder
mkdir /usr/share/phpmyadmin/tmp
2) findout your php user
<?php echo `whoami`; ?>
3) Change ownership of the tmp folder to the php user found in step 2
sudo chown -R step2phpuser:step2phpuser /usr/share/phpmyadmin/tmp
4) Signout of phpmyadmin and sign back in
I had the same error message. I'm using Ubuntu16.04 with lampp. You should go to 'phpmyadmin' directory, in my case '/opt/lampp/phpmyadmin/', create a new 'tmp' folder. Open a terminal window and:
cd YOUR_PATH_TO_PHPMYADMIN
sudo mkdir tmp
Now you have to change the group of the 'tmp' folder to give access to php user. In order to find it, you can create a php file inside your localhost directory, in my case 'htdocs'
sudo touch user.php
sudo nano user.php
Inside nano editor, type:
<?php echo `whoami`; ?>
Then press CTRL + O and CTRL + X to save and exit.
Open the browser and type in your address bar
localhost/user.php
It shows your php user.
After that, go to the terminal and navigate to your recently created 'tmp' directory inside phpmyadmin directory and type:
sudo chgrp YOUR_PHP_USER tmp -R
And change the permission to the 'tmp' directory:
sudo chmod 775 tmp -R
I recommend never give 777 permission to any file.
I hope it helps!
For Arch and Manjaro users:
Create a folder tmp at /etc/webapps/phpmyadmin/ - mkdir /etc/webapps/phpmyadmin/tmp
Set permission to 777 - chmod 777 /etc/webapps/phpmyadmin/tmp
Add this line to the config file at /etc/webapps/phpmyadmin/config.inc.php - $cfg['TempDir'] = '/tmp';
Cheers :)
I had the same problem but none of the answers above could solve.
In my case my php security settings was so strict protecting php to access directories out of scope defined in open_basedir located at my /etc/php.d/99-security.ini(which I added perviously from a security toturial and the settings also could be located at /etc/php.ini file in your case):
;; Limit PHP Access To File System
; Limits the PHP process from accessing files outside
; of specifically designated directories such as /var/www/html/
open_basedir="/home/:/etc/phpMyAdmin/:/var/lib/phpMyAdmin/"
change to:
open_basedir="/home/:/etc/phpMyAdmin/:/var/lib/phpMyAdmin/:'/usr/share/phpmyadmin/tmp/" ;<== changing to this solved the prblem
you just need to add your own directory in error mesage ('/usr/share/phpmyadmin/tmp/') and the end of open_basedir option. Don't forget placing separator : before adding it.
If the folder already exists for example from a previous installation:
chmod -R 777 PATH_TO_FOLDER
Therefore permission on subdirectories are also modified (recursively).
In my case [MacOs El Capitán/portuguese], the message was:
The $cfg['TempDir'] (./temp/) is not accessible
My solution, in xamppfiles/phpmyadmin/config.inc.php:
$cfg['TempDir'] = './temp/'; to $cfg['TempDir'] = '../temp/';
That is, I just added a point to the path... work's fine.
I just changed my vendor_config.php file to define('TEMP_DIR', '/tmp/'); instead of define('TEMP_DIR', './tmp/');
This seems to work.
I had a similiar problem, with the "temp" directory. The solution was to change the owner and group of the "twig" directory (inside "temp") to "apache" (both owner and group)
Create the tmp folder in the root of phpmyadmin files
In addition to that, you also need to provide all permissions to that folder. That's what I did in Windows.
My Answer goes to centos 7 Sentora users,
tmp folder has to be created under phpMyadmin of Sentora as shown below
cd /etc/sentora/panel/etc/apps/phpmyadmin/
sudo mkdir tmp
After creating the folder make sure you give Apache access permissions to the tmp folder
chown -R apache /etc/sentora/panel/etc/apps/phpmyadmin/tmp/
simply go to the phpmyadmin folder and put this code
$cfg['TempDir'] = './tmp/';
and then check tmp folder is exists or not into phpmyadmin if not exists then create tmp folder and give read and right permission to it.
For me, the error message was as follows:
The $cfg['TempDir'] (/var/lib/phpmyadmin/tmp/) is not accessible. phpMyAdmin is not able to cache templates and will be slow because of this
Then I navigate and checked the location. there was the tmp folder but was owned by www-data by default. After that, I make it writable by the user the PHP is running under. Problem solved.

How to make directory outside of current directory?

I'm trying to create a secure way to handle file uploads by uploading the files to a directory outside of public_html.
I'm testing my script and my script works when I execute sudo php receive_files.php, but when I run receive_files.php without sudo I get failed to open stream: Permission denied.
Right now all permissions all the way back to var/www/html/mysite/public_html are set to 755. I tried changing all of them to 775 and the command still didn't work
Without sudo. And I'm pretty sure that would not be secure. How do I get around this problem?
My code:
$encoded_file = $_POST['file'];
$user_id = $_POST['user_id'];
$decoded_file = base64_decode($encoded_file);
$new_directory = "../../../../../../user_uploads/$user_id/";
if(!file_exists($new_directory)){
mkdir($new_directory, 0775, true);
file_put_contents($new_directory . $decoded_file);
}
Sudo is required when you are not the owner of something or you try to change permissions. So if you want php script to have access to upper directory. Change the group or user owner of upper directory same as php executor, in most cases its www-data
You can check owner of php script by using
ls -al
Then change owner using
chown -hR www-data:www-data directorypath
For more detail check manual of chown command
This will most probably fix your issue
Additional info
specifying absolute path instead of relative path solved the issue

php writting to a file from a website not working

Im trying to write to file using php but it doesn't see to work.
$file = fopen("test.txt","w");
fwrite($file,"Hello World!");
fclose("$file");
I published the site using the school server. and the php file/text file are all in public_html folder. The problem is, running this into terminal writes the file. Running it as a website doesn't.
How do i fix this?
P.S. I've tried chmod 644, 777, 755
Remove the quotes in fclose :
$file = fopen("test.txt","w");
fwrite($file,"Hello World!");
fclose($file);
Also, you have to grant all permission : see that answer.
Hmm... is it a UNIX/Linux server?
You probably want to give the group www-data permissions to write the folder.
Assuming your web folder is /var/www, try doing this:
sudo chown `whoami`:www-data /var/www
sudo chmod 775 /var/www
And try again.
If you're working in your personal web folder (http://domain.ext/~yourusername), the commands should be:
chown `whoami`:www-data ~/public_html
chmod 775 ~/public_html
Does it work running the script now?

Codeigniter - move_uploaded_file permission(?) issue

This problem was asked before, but did not solve my case. I am working with Codeigniter.
I have a simple form that submits a file and want to move this file into a folder on my server. After submitting I can print_r the $_FILES['new-item-file'] array and everythings looks good.
But when I use move_uploaded_file I get an error:
failed to open stream: HTTP wrapper does not support writeable connections
The folder I want to write in exists and has 777 permissions.
Dies anyone have a solution to this?
Thanks a lot!
I solved it:
Move_uploaded_file does not seem to accept absolute paths. I took out the base_url(); and it worked.
This error happens due to two reasons.
Permission of the folder and invalid group and user owner.
Wrong path.
Permission and owner of folder :
If you are in Linux. Open terminal type this command. This will change the owner of the folder.
$ cd project_path && sudo chown -R www-data:www-data picture_folder/
Type this command to change the permission of folder.
$ sudo chmod -R 777 picture_folder/
note : Use man command more help about these commands.
$ man chmod OR man chown
Path of folder .
In codeigniter, index.php root file is executed. That is responsible for all activities. So don't use base_url() for root path. Instead. Just give root folder name. like
CI application
->
-application
-system
-user_guide
-index.php
-picture_folder
$target_directory="picture_folder/sub_folder";

PHP fopen can't create a file

I have a function in PHP language to create an xml file when requested.
if(($file= fopen("./include/catalogo.xml", "w"))==false){echo 'non creo il file'; return false;}
"catalogo.xml" can't be created, permission denied. I know I should try to change permissions, but how can do this if the file doesn't exist? Or, are there things that I ignored?
I think you might be ignoring the permissions of the directory (./include).
I'm assuming you are running this PHP via a web-server and on Linux (like Apache for example) - in which case the user account that is trying to create the file will be 'apache' or 'www-data' (or whatever user your webserver is running under).
On your server - have a look at the permissions of ./include - you need to do one of two things:
a) make ./include world writable (so the 'apache' user can now create a file inside of it).
b) change the owner or group of the ./include to 'apache' so it can create a file inside of it.
Your PHP is fine - it's the permissions of the folder it is trying to create the file inside of that is not.
You have to change the ownership of the directory "include" and set it to the web server's user and set the permission to a reasonable value:
$ sudo chow www-data include
$ sudo chmod 755 include
If you don't know which user your web-server is running by you can open the include dir permissions world-wide:
$ sudo chmod 1777 include
after create the creation of catalogo.xml you check the include diretory:
$ sudo ls -al include
-rwxr-xr-x 1 http web 4096 May 5 15:37 catalogo-xml
Now you can change the ownership of the directory "include" and set it to the web server's user (http) and reset the permission to a reasonable value:
$ sudo chow http include
$ sudo chmod 755 include
See also the manual of chmod, chown and ls:
$ man chmod
$ man chown
$ man ls
If you use the terminal and go to the parent of folder your file will be created in, which is the parent of the include folder and type in the command:
chmod 777 include
This should change the permissions of this folder so you won't receive the permission denied error anymore. If you do try this command:
chmod -R 777 include
