htmlspecialchars_decode()

htmlspecialchars_decode() is simple if you keep it on paper. Amit uses it for a htmlspecialchars_decode dry-run in a first job task.

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

Skip htmlspecialchars_decode() and skipping the failure case for htmlspecialchars_decode shows up in a first job task.

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

If a htmlspecialchars_decode dry-run breaks under htmlspecialchars_decode(), check skipping the failure case for htmlspecialchars_decode first.

Place htmlspecialchars_decode() next to nearby PHP work — one htmlspecialchars_decode step Amit can write from memory is the link.

Viva for htmlspecialchars_decode(): what it is → one htmlspecialchars_decode step Amit can write from memory → the mistake (skipping the failure case for htmlspecialchars_decode).

Exam tip

For htmlspecialchars_decode(): definition + a first job task + one failure.

Example

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

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