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

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

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

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

Viva — what is and (operator)? Then show the smallest and operator example you can type. Then name the trap.

Exam tip

What is and (operator)? Show this: the smallest and operator example you can type. Trap: only saying “and operator” with no example.

Example

<?php
// and
$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";
}

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