array_diff_ukey()

If you can teach array_diff_ukey() (function) using a array_diff_ukey function dry-run, you know it. If you only know the heading, you don’t.

For array_diff_ukey() (function), a .php page is in play. Don’t blame it until you have traced a array_diff_ukey function dry-run.

Without array_diff_ukey() (function), lab hour gets messy and a array_diff_ukey function dry-run is hard to trust.

Sara ships array_diff_ukey() (function) in lab hour. That is the use case worth saying.

If a array_diff_ukey function dry-run breaks under array_diff_ukey() (function), check only reciting the name of array_diff_ukey function first.

array_diff_ukey() (function) is not a lonely heading. Sara ties it to a array_diff_ukey function dry-run.

Viva for array_diff_ukey() (function): what it is → one array_diff_ukey function step Sara can write from memory → the mistake (only reciting the name of array_diff_ukey function).

Exam tip

Say array_diff_ukey() (function) in one breath, then one array_diff_ukey function step Sara can write from memory, then only reciting the name of array_diff_ukey function.

Example

<?php
// array_diff_ukey()
$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_ukey(): scores array, print avg, then high marks. Say the output.
