If I use the truncate on the tables I was to clear, it truncates it all the
way. It does not take me back to the fresh install. For example, doing
truncate on the "wp_term_taxonomy" table will get rid of the 2 taxonomies (
category + link_category) that comes with fresh install.

A more ideal solution is to backup from an exported xml file.

Something like this;


Does anyone know how to make that happen?

Daniel earlier mentioned that

mysql -u #username#  -p #database# < #dump_file#

would restore the database.

But how do I do this from a PHP code?
