File Handling

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

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

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

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

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

Exam tip

<?php
// File Handling
$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";
}
