Same name and namespace in other branches
  1. 8.0 core/includes/database.inc \db_table_exists()

Checks if a table exists.

Parameters

string $table: The name of the table in drupal (no prefixing).

Return value

bool TRUE if the given table 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 tableExists() on it. E.g. $injected_database->schema()->tableExists($table);
