1 bootstrap.inc backdrop_get_schema($table = NULL, $rebuild = FALSE)

Gets the schema definition of a table, or the whole database schema.

The returned schema will include any modifications made by any module that implements hook_schema_alter(). To get the schema without modifications, use backdrop_get_schema_unprocessed().


$table: The name of the table. If not given, the schema of all tables is returned.

$rebuild: If true, the schema will be rebuilt instead of retrieved from the cache.

Return value

array: The schema definition of the requested table.
