Date and Time

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

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

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

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

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

Exam tip

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

Example

<?php
// Date and Time
$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";
}

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