array_splice()

array_splice() (function) is simple if you keep it on paper. Asha uses it for a array_splice function dry-run in a small live site.

array_splice() (function) on the board: one array_splice function step Asha can write from memory. Then say what a array_splice function dry-run looks like after.

array_splice() (function) exists so Asha can keep a array_splice function dry-run correct in a small live site.

Use array_splice() (function) when a array_splice function dry-run must stay clear. If a simpler PHP step works, use that instead.

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

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

Viva for array_splice() (function): what it is → one array_splice function step Asha can write from memory → the mistake (copy-pasting array_splice function without a dry-run).

Exam tip

Board: a array_splice function dry-run. Dry-run array_splice() (function). Name the trap: copy-pasting array_splice function without a dry-run.

Example

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