Delete File

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

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

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

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

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