Exam tip

Board: Isha walking through array_diff_assoc function. Dry-run array_diff_assoc() (function). Name the trap: only reciting the name of array_diff_assoc function.

Example

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

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