array_values()

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

Keep array_values() (function) small. Asha should finish array_values function on Asha's board in a few lines, not a 40-line dump.

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

Use array_values() (function) when array_values function on Asha's board must stay clear. If a simpler PHP step works, use that instead.

array_values() (function) miss: copy-pasting array_values function without a dry-run. Fix it before you talk about advanced PHP.

After array_values() (function), Asha should still remember copy-pasting array_values function without a dry-run.

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

Exam tip

Board: array_values function on Asha's board. Dry-run array_values() (function). Name the trap: copy-pasting array_values function without a dry-run.

Example

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

Short notes

Defarray_values() (function) — Asha uses it for array_values function on Asha's board in a small live site.
Rulearray_values() (function) → one array_values function step Asha can write from memory.
Rememberarray_values() (function) + Apache/Nginx (a small live site).
Usearray_values() (function) in a small live site (array_values function on Asha's board).
Traparray_values() (function) — copy-pasting array_values function without a dry-run.
Exarray_values() (function) → array_values function on Asha's board.
