The `addForeignKeyConstraint` method is a part of the PHP Doctrine DBAL Schema component. This method is used to add a foreign key constraint to a table in a database schema.
A foreign key constraint ensures the integrity of the database by defining a relationship between two tables. It enforces that the values in one table's foreign key column must match the values in another table's primary key column.
By using the `addForeignKeyConstraint` method, you can specify the source column(s) in the current table, the referenced table, the referenced column(s), and options such as deletion and update rules.
This method simplifies the process of adding foreign key constraints to database tables and helps maintain referential integrity in the database schema.
