The default storage engine is based on the parameters chosen when the MySQL was installed. There are 3 methods in installation. 2 methods use InnoDB as the default, and 1 uses MyISAM as the default. It can be either one. To find out, make a database in phpMyAdmin, then click to add a table and at the bottom the default will always be chosen/displayed where which you can then select the engine of your preference.
