Namedba_replace — Replaces the value of an existing key-value pair (or inserts a new key-value pair) in the database.
dba_replace() replaces or inserts a key-value pair in a db file. If the key-value pair exists, the value is overwritten with the value contained in the value argument. If the key doesn't exist, the function behaves like dba_insert() , adding a new key-value pair to the database.
If a pair is successfully replaced or inserted, the function returnsTRUE. In all other cases, the function fails and returnsFALSE.
To insert a key-value pair
