PHP Help, Stripping HTML tags and updating MySQL.

[speedway]

Hi all

I am looking for a bit of help in PHP. For my forums DB, I want to programatically update every posts content with the same content minus all the HTML tags. Basically a small PHP app to

connect to Mysql,
open the post table,
extract the pagetext value,
strip all HTML tags from it
write it back to that record
loop to the next record.

Due to my distinct lack of PHP knowledge I am struggling with the looping bit and retrieve/modify/update bit, so I appreciate some kind soul showing me the right direction.

Thanks in advance

Cheers
Bruce
