crypt()

If you can teach crypt() using a crypt dry-run, you know it. If you only know the heading, you don’t.

crypt() order — meaning → one crypt step Zara can write from memory → one limit. Dumping ten features helps nobody.

Skip crypt() and only reciting the name of crypt shows up in a first job task.

Zara ships crypt() in a first job task. That is the use case worth saying.

If a crypt dry-run breaks under crypt(), check only reciting the name of crypt first.

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

Close crypt() with — “If I skip it, a crypt dry-run goes wrong like this: only reciting the name of crypt.”

Exam tip

Say crypt() in one breath, then one crypt step Zara can write from memory, then only reciting the name of crypt.

Example

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

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

Short notes

Defcrypt() — Zara uses it for a crypt dry-run in a first job task.
Rulecrypt() → one crypt step Zara can write from memory.
Remembercrypt() + a .php page (a first job task).
Usecrypt() in a first job task (a crypt dry-run).
Trapcrypt() — only reciting the name of crypt.
Excrypt() → a crypt dry-run.
