this is "magic quotes" a waste of time, and kinda dangerous.
you can use stripslashes to remove the slashes, 2 more come because
once there is one, it is seen by the next function along and gets
preserved, how do you preserve a backslash? you add 2 backslashes, one
to escape the original one, and a second to escape the 2nd to show
that it is to be interpreted as "real"
As I say this is a config issue, you can probably set magic quotes to
off using ini_set, which I recommend, you are then responsible for
filtering and managing user input, but at least it becomes more
predictable.
