ok ... normally the php.ini file should be within your www or public_html folder (w/e yours is called)...
make a php file with this code in it.
Code:
<?php
echo getcwd();
?>
save the file as say ... path.php and place it in the dir with the php.ini , which as I said is usually within the HTML folders... go to the path.php file...(e.g.
www.yoursite.com/path.php) and it will give you the path to that dir... say for example (bradleyw/home/public_html) and just add the php.ini to that listed path.
attached is the path.php file if you are too lazy to make it yourself
