htmlentities()

htmlentities() is simple if you keep it on paper. Asha uses it for htmlentities on Asha's board in a viva board.

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

htmlentities() exists so Asha can keep htmlentities on Asha's board correct in a viva board.

Asha ships htmlentities() in a viva board. That is the use case worth saying.

Don’t do this with htmlentities() — copy-pasting htmlentities without a dry-run. Interviewers spot it in ten seconds.

htmlentities() is not a lonely heading. Asha ties it to htmlentities on Asha's board.

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

Exam tip

For htmlentities(): definition + a viva board + one failure.

Example

<?php
// htmlentities()
$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";
}

htmlentities(): scores array, print avg, then high marks. Say the output.

Short notes

Defhtmlentities() — Asha uses it for htmlentities on Asha's board in a viva board.
Rulehtmlentities() → one htmlentities step Asha can write from memory.
Rememberhtmlentities() + a .php page (a viva board).
Usehtmlentities() in a viva board (htmlentities on Asha's board).
Traphtmlentities() — copy-pasting htmlentities without a dry-run.
Exhtmlentities() → htmlentities on Asha's board.
