No quotes for numbers constant

In this video Paulk doesn't use quotes for the numbers while for the text yes. Why?

Es:

<?php
define("YEAR", 2015);
define("JOB_TITLE", "Teacher")
define("MAX_BADGES", 150000);
?>

Thanks

If he would have used quotes on the numbers they would be a string(type) instead of an integer(type). Booleans and Floats are two other types you wouldn't use quotes for.

Strings would be used for a word or sentence. While integers and floats(decimal numbers) would be used for math and other things you would use a number for.
