HTTP_REFERER storing in mysql

hi,

How do need to / how do i   validate HTTP_REFERER?
is it safe to store HTTP_REFERER in mysql using only mysql_real_escape_string?

I want to store the referer into my database.  is this safe enough?
$referer                =   getenv(HTTP_REFERER);
$sql    =   sprintf("INSERT INTO referer_table(`referer_id`, `referer`) VALUES('', '%s') ",
                                                    mysql_real_escape_string($referer));

Concerned about SQL injection.

Hi,

headers can be forged, to be on the safe side I would be escaping this value - or at least using htmlentities.

Your statement is SQL-injection safe due to the mysql_real_escape_string (yes it's sufficient). If you display values from that table make sure to escape/quote the values correctly you display.

Thank you both.

I had read in different places that the headers can be forged and that is what was causing my concern.

cheers.
