If you have multiple websites in the same domain folder and only want to enable or disable php settings only for a certain website, create a file .user.ini
inside the website folder.
In the file set the desired php values, for example:
set post and upload max file size:
upload_max_filesize = 200M
post_max_size = 200M
display all php errors:
error_reporting = E_ALL
display_errors = on
After editing you need to restart the php service. Navigate to PHP.INI editor and select the php version that your domain is using. Simply click on the save button and the service will be restarted, immediately applying settings from the .user.ini
file.
