function db_field_names
db_field_names($fields)
Returns an array of field names from an array of key/index column specifiers.
This is usually an identity function but if a key/index uses a column prefix specification, this function extracts just the name.
Parameters
array $fields: An array of key/index column specifiers.
Return value
array An array of field names.
Deprecated
as of Drupal 8.0.x, will be removed in Drupal 9.0.0. Instead, get a database connection injected into your service from the container, get its schema driver, and call fieldNames() on it. For example, $injected_database->schema()->fieldNames($fields);
