What the error message says. $this is a special variable that you can't just assign values to. Call it something else.

Also, since you're a Newbie, see the Guidelines in the Newbies' Forum.

you are using $this as genera variable for assign value. that's why u are getting error message.
you can not use this as simple variable it is a key word which is used for specific purpous.

you are new in php you should read php manual in which there are all convention of variable declaring are defined.
