php.ini changes, but not effective on Ubuntu

I have solved my question.

There is a syntax error in php.ini in line 109, so the next all syntax does not execute.

There is a good chance you didn't have permissions to modify the php.ini file. If you just browse to it via a normal folder window and click it Gedit (or whatever your default text editor is) won't be able to open it with write permissions.

You should be able to get away by sudo nano /etc/php5/apache2/php.ini (then your password at the prompt) and then changing the variables. Then be sure to write out (Ctrl + O) or make sure you confirm the save on exit.

For anyone wondering why the php.ini modification is not applied even after all directives are fine and restarting the apache on ubuntu, try restarting apache with sudo

sudo service apache2 restart

I have the same problem and this solve it I have foound php.ini inside folder /etc/php5/cli/php.ini I make changes to it

and restart apache sudo apache2ctl restart

I have already change /etc/php5/apache2/php.ini and restart apache by using sudo service apache2 restart but symfony doesn't see changes

I write it , it may help anyone

Here is how I solved this issue on Ubuntu after about three hours of debugging (PHP 7)

Steps

1. Run phpinfo() function and observe where the loaded PHP configuration file (php.ini) is

   

2. 'cd' into that directory and update it to the new values

3. Reboot your server

4. It works!
