array_unshift()

If you can teach array_unshift() (function) using array_unshift function on Zara's board, you know it. If you only know the heading, you don’t.

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

array_unshift() (function) exists so Zara can keep array_unshift function on Zara's board correct in lab hour.

array_unshift() (function) shows up in lab hour. Name array_unshift function on Zara's board, not “a real-world scenario”.

array_unshift() (function) miss: only reciting the name of array_unshift function. Fix it before you talk about advanced PHP.

array_unshift() (function) is not a lonely heading. Zara ties it to array_unshift function on Zara's board.

One breath for array_unshift() (function), then array_unshift function on Zara's board, then only reciting the name of array_unshift function. Sit down.

Exam tip

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

Example

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