money_format()

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

Keep money_format() small. Amit should finish a money_format dry-run in a few lines, not a 40-line dump.

Skip money_format() and only reciting the name of money_format shows up in a viva board.

Amit ships money_format() in a viva board. That is the use case worth saying.

money_format() trap — only reciting the name of money_format. Amit loses marks for that every viva.

After money_format(), Amit should still remember only reciting the name of money_format.

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

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

Example

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

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