array_uintersect() (function) is simple if you keep it on paper. Zara uses it for Zara walking through array_uintersect function in a viva board.

For array_uintersect() (function), the PHP runtime is in play. Don’t blame it until you have traced Zara walking through array_uintersect function.

Without array_uintersect() (function), a viva board gets messy and Zara walking through array_uintersect function is hard to trust.

Use array_uintersect() (function) when Zara walking through array_uintersect function must stay clear. If a simpler PHP step works, use that instead.

Don’t do this with array_uintersect() (function): only reciting the name of array_uintersect function. Interviewers spot it in ten seconds.

array_uintersect() (function) is not a lonely heading. Zara ties it to Zara walking through array_uintersect function.

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

Exam tip

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

Example

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