number_format()

number_format() is a PHP topic. In plain words you use it for a short number_format example in a college portal page. Don’t start with a slogan — start with that picture.

Smallest example: the smallest number_format example you can type. Type it, run it, and say what you see. If you can do that from memory, you know number_format().

From the example next to this theory — number_format(): scores array, print avg, then high marks.

Trap — only saying “number_format” with no example. Fix that before you talk about advanced PHP.

Viva — what is number_format()? Then show the smallest number_format example you can type. Then name the trap.
