wordpress | rights | apache2 - Correct permissions for /var/www and wordpress - Ask Ubuntu

First, you should ensure that your username is included in www-data group. If not, you can add your username as www-data group

sudo adduser $USER www-data

After that, you should change the ownership of /var/www to your username

sudo chown $USER:www-data -R /var/www

or   
sudo chown $USER:www-data -R /var/www/html/yourdirectory

Next step, for general practice, you should change permission to 755 (rwxr-xr-x), not recommend changing permission to 777 for security reason

sudo chmod u=rwX,g=srX,o=rX -R /var/www

or

sudo chmod u=rwX,g=srX,o=rX -R /var/www/html/yourdirectory

Related to specific permission for wordpress or laravel or another framework, then you can read the documentation respectively.
