PHP file_put_contents failed to open stream: Permission denied

Hmmm, that's weird well actually everything was working in my system. When I deployed the application to production facing this weird issue. Ya, I know the feeling.

You can quickly overcome this kind of PHP issues in the following ways:

Solution 1 - Check proper permission

Solution 2 - Check the owner of the folder

Solution 1 - Check proper permission

When you want to write to the files with PHP scripts the file or folder path won't be having proper write permissions. You can fix it with the following

chmod -R 777 file_or_folder_name

NOTE: Kindly check if 555 or 755 or 775 will work first

---

Solution 2 - Check the owner of the folder

Sometimes in all the project paths, you will encounter this kind of issue. Then check if the owner of the project is www-data or not.

If not then run the following command

sudo chown -R www-data:www-data /var/www/html

Here I have changed the owner group of html to www-data. Make sure to cross-verify your folder before changing the owner.
