Real 4 researche help
I know someone has already quoted system_meltdowns article before on a different thread, but this should be all the php research you need to complete the challenge.
Part four: Removing Ghost's record Now if you know the basics of php you will find this kind of easy, so we know where the records are now right? Goooood now we need to remove them so try things on the lines of all.php?(action)=(thing)&&id=(something) and remember we're trying to remove one record not loads of records. If you manage to remove his record you will get a password, we will need this soon. Worked for me :)
