Date Formatting

If you can teach Date Formatting using a Date Formatting dry-run, you know it. If you only know the heading, you don’t.

For Date Formatting, a .php page is in play. Don’t blame it until you have traced a Date Formatting dry-run.

Without Date Formatting, a first job task gets messy and a Date Formatting dry-run is hard to trust.

Use Date Formatting when a Date Formatting dry-run must stay clear. If a simpler PHP step works, use that instead.

Date Formatting miss — skipping the failure case for Date Formatting. Fix it before you talk about advanced PHP.

After Date Formatting, Sara should still remember skipping the failure case for Date Formatting.

Close Date Formatting with: “If I skip it, a Date Formatting dry-run goes wrong like this: skipping the failure case for Date Formatting.”

Exam tip

For Date Formatting: definition + a first job task + one failure.

Example

<?php
// Date Formatting
$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";
}

Date Formatting: scores array, print avg, then high marks. Say the output.
