You have the string " ' \ "
With addslashes it becomes " '\ \\ "
When you insert it into the database
it goes into a query like this
"update table set field=' '\ \\ ' "
But that inserts into the field only " ' \ ",
in other words the original string.
It is a normal behaviour and you should
omit the stripslashes function.
Hope it helps
