In fact, a primary key is just an unique key with the name PRIMARY. If no primary key is defined MySQL will δ×use first unique key as primary key if there is one.

You can create the primary key when creatσ©₽ing the table (in phpMyAdmin just chec¥ €€k the primary key radi'&o buttons for each field yo¥γε‌u wish to be part of t×&βhe primary key).

You can also add a primary key to an existin"‌g table with ALTER TABLE or CREATE INDEX (in phpMyAdmin you can just click on ‘add index×β’ on the table structure page below the listed ‍‍fields).
