Traits

  • Traits is a PHP topic. In plain words you use it for a short Traits example in a college portal page. Don’t start with a slogan — start with that picture.
  • Smallest example: the smallest Traits example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Traits.
  • From the example next to this theory: Traits: scores array, print avg, then high marks.
  • Trap: only saying “Traits” with no example. Fix that before you talk about advanced PHP.
  • Viva: what is Traits? Then show the smallest Traits example you can type. Then name the trap.

echo "avg=" . number_format($avg, 1) . "\n";
foreach ($scores as $s) {
  if ($s >= 80) echo "high: $s\n";
}
