array_product()

Zara only reaches for array_product() (function) when array_product function on Zara's board has to stay correct in a small live site.

array_product() (function) order: meaning → one array_product function step Zara can write from memory → one limit. Dumping ten features helps nobody.

Skip array_product() (function) and copy-pasting array_product function without a dry-run shows up in a small live site.

Zara ships array_product() (function) in a small live site. That is the use case worth saying.

If array_product function on Zara's board breaks under array_product() (function), check copy-pasting array_product function without a dry-run first.

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

Close array_product() (function) with: “If I skip it, array_product function on Zara's board goes wrong like this: copy-pasting array_product function without a dry-run.”

Exam tip

Say array_product() (function) in one breath, then one array_product function step Zara can write from memory, then copy-pasting array_product function without a dry-run.

Example

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