Date and Time

Don’t start Date and Time with jargon. Start with Arun walking through Date and Time. That is the whole point.

Keep Date and Time small. Arun should finish Arun walking through Date and Time in a few lines, not a 40-line dump.

Without Date and Time, a first job task gets messy and Arun walking through Date and Time is hard to trust.

Date and Time shows up in a first job task. Name Arun walking through Date and Time, not “a real-world scenario”.

Date and Time miss — only reciting the name of Date and Time. Fix it before you talk about advanced PHP.

Place Date and Time next to nearby PHP work — one Date and Time step Arun can write from memory is the link.

Close Date and Time with: “If I skip it, Arun walking through Date and Time goes wrong like this: only reciting the name of Date and Time.”

Exam tip

Say Date and Time in one breath, then one Date and Time step Arun can write from memory, then only reciting the name of Date and Time.

Example

<?php
// Date and Time
$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 and Time: scores array, print avg, then high marks. Say the output.

Short notes

DefDate and Time — Arun uses it for Arun walking through Date and Time in a first job task.
RuleDate and Time → one Date and Time step Arun can write from memory.
RememberDate and Time + the PHP runtime (a first job task).
UseDate and Time in a first job task (Arun walking through Date and Time).
TrapDate and Time — only reciting the name of Date and Time.
ExDate and Time → Arun walking through Date and Time.
