metaphone()

metaphone() is simple if you keep it on paper. Zara uses it for Zara walking through metaphone in a viva board.

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

Without metaphone(), a viva board gets messy and Zara walking through metaphone is hard to trust.

metaphone() shows up in a viva board. Name Zara walking through metaphone, not “a real-world scenario”.

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

After metaphone(), Zara should still remember copy-pasting metaphone without a dry-run.

Close metaphone() with: “If I skip it, Zara walking through metaphone goes wrong like this: copy-pasting metaphone without a dry-run.”

Exam tip

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

Example

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

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

Short notes

Defmetaphone() — Zara uses it for Zara walking through metaphone in a viva board.
Rulemetaphone() → one metaphone step Zara can write from memory.
Remembermetaphone() + a .php page (a viva board).
Usemetaphone() in a viva board (Zara walking through metaphone).
Trapmetaphone() — copy-pasting metaphone without a dry-run.
Exmetaphone() → Zara walking through metaphone.
