Maintain large customer need special trick, specially with “security in mind”
Many free host ( support php and mysql ) set restriction policy for security reason. Then phpinfo() is your friend to find out setting in server host.
Just make simple file in browser :
save it as info.php
see it from browser

Pay attention to those directive :
register_globals = Off
Safe mode = On
In many hosting place (paid hosting) the values are :
register_globals = On
Safe mode = Off

Each source need to identified it’s source.
GET, POST, SESSION, SERVER need to handle in that way.
it’s good for security.
How about “safe mode” ?
