flat file db help..simple question? Can't Post
lol i think this is kind of a newbie question but i didnt think it was newbie enough for the begginer section.

I have a flat file db, I want to delete a specific line of the flat file db.. what would be the code for this?

------------
-----example
------------
style: 3 fields, id,name,url split by the | character.

1|JOHN|http://johnsurl.com
2|ARSONE|http://arsone.com
3|SOMEONES_NAME|http://a-site.net

lets just say i want to delete id #2 (2|ARSONE|http://arsone.com) how would i delete that whole line. Thanks for taking the time to read.
