Append File

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

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

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

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

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

Exam tip

Example

<?php
// Append File
$scores = [80, 90, 70];
$avg = array_sum($scores) / count($scores);
echo "avg=" . number_format($avg, 1) . "\n";
foreach ($scores as $s) {
  if ($s >= 80) echo "high: $s\n";
}

Append File: scores array, print avg, then high marks. Say the output.
