array_unique()

Asha only reaches for array_unique() (function) when Asha walking through array_unique function has to stay correct in a small live site.

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

Without array_unique() (function), a small live site gets messy and Asha walking through array_unique function is hard to trust.

array_unique() (function) shows up in a small live site. Name Asha walking through array_unique function, not “a real-world scenario”.

array_unique() (function) trap — only reciting the name of array_unique function. Asha loses marks for that every viva.

array_unique() (function) is not a lonely heading. Asha ties it to Asha walking through array_unique function.

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

Exam tip

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

Example

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