array_udiff_assoc()

Sara only reaches for array_udiff_assoc() (function) when array_udiff_assoc function on Sara's board has to stay correct in a viva board.

Do array_udiff_assoc() (function) once by hand. one array_udiff_assoc function step Sara can write from memory. Change one input. Say the new result out loud.

Without array_udiff_assoc() (function), a viva board gets messy and array_udiff_assoc function on Sara's board is hard to trust.

array_udiff_assoc() (function) shows up in a viva board. Name array_udiff_assoc function on Sara's board, not “a real-world scenario”.

If array_udiff_assoc function on Sara's board breaks under array_udiff_assoc() (function), check copy-pasting array_udiff_assoc function without a dry-run first.

After array_udiff_assoc() (function), Sara should still remember copy-pasting array_udiff_assoc function without a dry-run.

One breath for array_udiff_assoc() (function), then array_udiff_assoc function on Sara's board, then copy-pasting array_udiff_assoc function without a dry-run. Sit down.

Exam tip

Say array_udiff_assoc() (function) in one breath, then one array_udiff_assoc function step Sara can write from memory, then copy-pasting array_udiff_assoc function without a dry-run.

Example

<?php
// array_udiff_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_udiff_assoc(): scores array, print avg, then high marks. Say the output.
