Default Arguments

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

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

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

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

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

Exam tip

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

Example

<?php
// Default Arguments
$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";
}

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