PHP显示SQL数据和重复的次数

I have a table called 'event1' containing info such as:

| Name | Age | Nationality |

I want to display, for instance, a nationality and how many times a certain nationality is repeated.

So for example:
India - 5
Australia - 10
US - 10

The query I came up with was

SELECT nationality, COUNT(nationality) AS Total
FROM event1 GROUP BY nationality HAVING COUNT(nationality)>=1

I'm not sure if that is correct.

How can I display the above example using PHP?
