Removes rewrite rules and then recreate rewrite rules.

$hard bool Optional

Whether to update .htaccess (hard flush) or just update rewrite_rules option (soft flush). Default is true (hard).

Default: true

This function is useful when used with custom post types as it allows for automatic flushing of the WordPress rewrite rules (usually needs to be done manually for new custom post types). However, this is an expensive operation so it should only be used when necessary.
