array_pop()

Zara only reaches for array_pop() (function) when a array_pop function dry-run has to stay correct in a viva board.

Keep array_pop() (function) small. Zara should finish a array_pop function dry-run in a few lines, not a 40-line dump.

Skip array_pop() (function) and skipping the failure case for array_pop function shows up in a viva board.

Zara ships array_pop() (function) in a viva board. That is the use case worth saying.

If a array_pop function dry-run breaks under array_pop() (function), check skipping the failure case for array_pop function first.

Place array_pop() (function) next to nearby PHP work — one array_pop function step Zara can write from memory is the link.

Viva for array_pop() (function): what it is → one array_pop function step Zara can write from memory → the mistake (skipping the failure case for array_pop function).

Exam tip

Board: a array_pop function dry-run. Dry-run array_pop() (function). Name the trap: skipping the failure case for array_pop function.

Example

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