wpdb::tables() │ public │ WP 3.0.0

Returns an array of WordPress tables.

Also allows for the CUSTOM_USER_TABLE and CUSTOM_USER_META_TABLE to override the WordPress users and usermeta tables that would otherwise be determined by the prefix.

The $scope argument can take one of the following:

• 'all' - returns 'all' and 'global' tables. No old tables are returned.
• 'blog' - returns the blog-level tables for the queried blog.
• 'global' - returns the global tables for the installation, returning multisite tables only on multisite.
• 'ms_global' - returns the multisite global tables, regardless if current installation is multisite.
• 'old' - returns tables which are deprecated.

Метод класса: wpdb{}

No Hooks.

Return

String[]. Table names. When a prefix is requested, the key is the unprefixed table name.
