setlocale() miss — copy-pasting setlocale without a dry-run. Fix it before you talk about advanced PHP.

Place setlocale() next to nearby PHP work — one setlocale step Sara can write from memory is the link.

Viva for setlocale(): what it is → one setlocale step Sara can write from memory → the mistake (copy-pasting setlocale without a dry-run).

<?php
// setlocale()
$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";
}

setlocale(): scores array, print avg, then high marks. Say the output.
