hello, need some help with php vs. vb

[maoreactor]

hmm another question, as i see, in order to recognize a catagory, it looks like this:

childlist: 1-,10,4,5
as i dont know what 1- says, the 2nd parameter is the current forumid and 4 and 5 is the child forums of this catagory.

now, how do i make the script know that this forumid has child forums? like,
if ($row['childlist] ?HAS MORE THEN 2 PARAMS?)
{
$num=number of childforums;
$parentid = forumdid of parent;
$childforum[1] = forumid;
$childforum[2] = forumid;
...
}

i have read $array guide at php.net and dont seem to get it...

my main idea is that it will look like this:

CATAGORY: CATAGORY:
forum1 forum1
forum2 forum2
forum3 forum3

CATAGORY: CATAGORY:
forum1 forum1
forum2 forum2
forum3 forum3

thanks for your help
