category structure

anyone have any ideas on this I have a table of directory categories id | parentid | category so... 1 | 0 | blah1 top 2 | 1 | blah2 sub 3 | 1 | blah3 sub2 4 | 3 | blah4 sub2->sub I want to hit the DB only once so i select all and drop into array Now i've created array with these like so: $category[$parentid][$id] But now what? trouble is that $msub[2][4] is a sub category of $msub[1][2] so i can't just run thru and print the array - need to manipulate a little. Any ideas? [or even a beeter way to do this?] thanks olinux __________________________________________________ Do You Yahoo!? Make a great connection at Yahoo! Personals. http://personals.yahoo.com
