Type Hinting

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

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

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

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

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

Exam tip

What is Type Hinting? Show this: the smallest Type Hinting example you can type. Trap: only saying “Type Hinting” with no example.

Example

<?php
// Type Hinting
$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";
}

Type Hinting: scores array, print avg, then high marks. Say the output.
