function db_index_exists
db_index_exists($table, $name)
Checks if an index exists in the given table.
Parameters
string $table: The name of the table in drupal (no prefixing).
string $name: The name of the index in drupal (no prefixing).
Return value
bool TRUE if the given index exists, otherwise FALSE.
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 indexExists() on it. For example, $injected_database->schema()->indexExists($table, $name);
