If the array you are imploding is empty, implode returns {null}, not an empty string. This can be a
concern if you are imploding a dynamically generated array to place in a database. If you get a
null and the database field is set to NOT NULL, you get a contstraint violation. This has happened
to me with prepared queries in which the system trys to figure out how to send the data to the
database.
