Download File

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

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

From the example next to this theory — Download File: scores array, print avg, then high marks.

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

Viva — what is Download File? Then show the smallest Download File example you can type. Then name the trap.
