Date being changed when updating MySQL field

Question

I'm running into a weird issue where I'm posting a date in Ymd format yet it's being changed to a completely different date once I view in the actual MySQL table.

Here's the query

UPDATE $admins_table 
SET    expire=$expireu 
WHERE  identity='$donation_row[steam_id]

The expire field is what I'm having issues with. The field itself is a varchar, and the $expireu variable is always a date in Ymd format ex. 2013-11-16

When that query is run, with the date I gave as an example above, I get a weird result in the actual MySQL table. If I go to view the table, instead of it storing 2013-11-16 it has stored 1986 as the date. No month or day, just 1986 .

I may have made a very stupid/silly mistake, but at this point I'm unsure of what I've flubbed. Any help in the right direction would be much appreciated, thank you.

Answer 1

haha, use quotes!

UPDATE $admins_table SET expire='$expireu' WHERE identity='$donation_row[steam_id]'

mysql substracts 2013-11-16 == 1986
