str_rot13()

str_rot13() is a PHP topic. In plain words you use it for a short str_rot13 example in a college portal page. Don’t start with a slogan — start with that picture.

Smallest example: the smallest str_rot13 example you can type. Type it, run it, and say what you see. If you can do that from memory, you know str_rot13().

From the example next to this theory — str_rot13(): scores array, print avg, then high marks.

Trap — only saying “str_rot13” with no example. Fix that before you talk about advanced PHP.

Viva — what is str_rot13()? Then show the smallest str_rot13 example you can type. Then name the trap.

Exam tip

What is str_rot13()? Show this: the smallest str_rot13 example you can type. Trap: only saying “str_rot13” with no example.

Example

<?php
// str_rot13()
$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";
}

str_rot13(): scores array, print avg, then high marks. Say the output.
