fopen Permission denied, Ubuntu, CodeIgniter

Question

I was trying fopen for my project. Which running on Ubuntu with CodeIgniter PHP framework. The result was like this:

A PHP Error was encountered
Severity: Warning
Message: fopen(testFile.txt): failed to open stream: Permission denied
Filename: controllers/home.php
Line Number: 10

can't open file

By the way, here are my code on Controller:

public function create_file(){
    $ourFileName = 'testFile.txt';
    $ourFileHandle = fopen($ourFileName, 'r') or die ("can't open file");
    fclose($ourFileHandle);
}

I looked at that code, and I thought that there is should be a path where I open the file, right? If yes, where should I put the path? Because, I followed this code from this tutorial: http://www.tizag.com/phpT/filecreate.php.

One thing that make me confuse is, there is no file testFile.txt and I wanna create it, but how to give the permission to create it. Because terminal will say No such file or directory for the file. What should I do?

I've also tried to run the chmod on www directory. But, it still didn't work. Hope anyone help me to handle this problem. Thank you...

Solution

There are 2 ways :

1.) chmod www directory to 777 by this command "sudo chmod -R 777 /var/www". This will give permissions recursively to all sub-folders and files.

2.) If you create any new folders (or projects in www directory) in future after the 1st step , then follow above :

=> Right click on your current project folder
=> Scroll to Properties
=> Scroll to permissions
=> Add permission for "Create and Delete files" for owner, group, others.
=> Now click on "Change permission for enclosed files"
=> Give appropriate permissions for files and folders there.

All done. Now fopen() should not give that warning.

Thank you for your advice, Hari. I've tried it, but when I clicked on "Change Permission for enclosed files" the file access turned to none (--). what should I do?

You are searching that file on the same directory that your .php file. Do you realize that? So you have to go to that directory which your .php file placed, and create a file in that directory.

Hello Nana, First of all chmod www directory to 777 by this command "sudo chmod -R 777 /var/www" , after that follow the above process. My answer modified.

if the file is not already created you should open it with write mode, which creates the file if not already created. $handle = fopen("testFile.txt", "w"); // for writing. I have edited my post including changes need to be done in your code. One more thing if file is not already present why you what to read from it. One will only read from a file which exists.
