quoted_printable_encode()

quoted_printable_encode() is simple if you keep it on paper. Asha uses it for Hello, Asha in a web page.

Do quoted_printable_encode() once by hand. echo / print. Change one input. Say the new result out loud.

Skip quoted_printable_encode() and missing semicolon shows up in a web page.

Use quoted_printable_encode() when Hello, Asha must stay clear. If a simpler PHP step works, use that instead.

If Hello, Asha breaks under quoted_printable_encode(), check missing semicolon first.

quoted_printable_encode() is not a lonely heading. Asha ties it to Hello, Asha.

Viva for quoted_printable_encode() — what it is → echo / print → the mistake (missing semicolon).

Exam tip

For quoted_printable_encode(): definition + a web page + one failure.

Example

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

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