  • $query = "INSERT INTO cats VALUES(NULL, 'Cougar', 'Growler', 2)"; $query = "INSERT INTO cats VALUES(NULL, 'Cheetah', 'Charly', 3)"; By the way, notice the NULL value passed as the first parameter? This is done because the id column is of the AUTO_INCREMENT type and MySQL will decide what value to assign according to the next available number in sequence, so we simply pass a NULL value, which will be ignored. Of course, the most efficient way to populate MySQL with data is to create an array and insert the data with a single query. Retrieving Data Now that some data has been entered into...
