If you want to enable PHP settings for all Directories under your account by using “php.ini” file , say if you want to enable these two functions for all your directories :
allow_url_fopen = On
allow_url_include = On
then just add the following code in the .htaccess file :
SetEnv PHPRC “/home/username/public_html”
Note : Replace the username with the domain username .
that’s all this will do it.
