explode()

[sabret00the]

i've always managed to avoid this up until now but now i really need it.

basically i want to check is a table column has a value, if it does, i need to explode it

so up to here i gues it's

PHP Code:

if ($bbuserinfo[grps])
 {
     $grps_ids = explode(' ', trim($bbuserinfo['grps'])); 


but once it's exploded how do i check the values?

with a query i'm guessing i could've used the FIND_IN_SET but i'm really trying to limit the queries at this stage

also how would i go about updating such a column? would it simply be

PHP Code:

UPDATE user SET grps = $bbuserinfo[grps] + $newvalue 


?
