Parent , Child Category Tree

Php Code: Parent , Child Category Tree

Next Code

This is a simple PHP script to generate a Category Tree structure based on parent/child MySQL database. Database structure looks like this:

- category_id
- parent_id
- title

And will generate a structure like this:

Category 1
- Sub Category
- Sub, Sub Category
- Sub Category 2
Category 2

This is much simpler and works very well. The other code I found on this forum didn't work at all and was very complicated, so I wrote an easy script. Just 1 note: It's meant for a structure that does not have a root element.
