Variable Arguments

Zara only reaches for Variable Arguments when $marks = 72 has to stay correct in a result script.

Keep Variable Arguments small. Zara should finish $marks = 72 in a few lines, not a 40-line dump.

Variable Arguments exists so Zara can keep $marks = 72 correct in a result script.

Variable Arguments shows up in a result script. Name $marks = 72, not “a real-world scenario”.

Variable Arguments trap — using marks without $. Zara loses marks for that every viva.

Variable Arguments is not a lonely heading. Zara ties it to $marks = 72.

One breath for Variable Arguments, then $marks = 72, then using marks without $. Sit down.

Exam tip

For Variable Arguments: definition + a result script + one failure.

Example

<?php
// Variable 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";
}

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