array_pad()

Ananya only reaches for array_pad() (function) when a array_pad function dry-run has to stay correct in lab hour.

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

Without array_pad() (function), lab hour gets messy and a array_pad function dry-run is hard to trust.

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

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

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

Close array_pad() (function) with: “If I skip it, a array_pad function dry-run goes wrong like this: copy-pasting array_pad function without a dry-run.”

Exam tip

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

Example

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

Short notes

Defarray_pad() (function) — Ananya uses it for a array_pad function dry-run in lab hour.
Rulearray_pad() (function) → one array_pad function step Ananya can write from memory.
Rememberarray_pad() (function) + Apache/Nginx (lab hour).
Usearray_pad() (function) in lab hour (a array_pad function dry-run).
Traparray_pad() (function) — copy-pasting array_pad function without a dry-run.
Exarray_pad() (function) → a array_pad function dry-run.
