Autoloading

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

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

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

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

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

Exam tip

$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";
