Comments

Comments is a PHP idea you prove with Arun walking through Comments, not with a slogan.

Comments order — meaning → one Comments step Arun can write from memory → one limit. Dumping ten features helps nobody.

Without Comments, lab hour gets messy and Arun walking through Comments is hard to trust.

Comments shows up in lab hour. Name Arun walking through Comments, not “a real-world scenario”.

Don’t do this with Comments — only reciting the name of Comments. Interviewers spot it in ten seconds.

Comments is not a lonely heading. Arun ties it to Arun walking through Comments.

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

Exam tip

For Comments: definition + lab hour + one failure.

Example

<?php
// Comments
$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";
}

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

Short notes

DefComments — Arun uses it for Arun walking through Comments in lab hour.
RuleComments → one Comments step Arun can write from memory.
RememberComments + the PHP runtime (lab hour).
UseComments in lab hour (Arun walking through Comments).
TrapComments — only reciting the name of Comments.
ExComments → Arun walking through Comments.
