To begin using php in combination with an Oracle database with your web account you must first obtain an Oracle - Academic Database account by filling out a Computer Account Request Form.
Once you have an account you can create new tables in your database. For this example a table named TEST_TABLE was created which contains four columns: id, name, email, and phone. A sequence was added to increment the id field.
