Mail

Mail is a PHP idea you prove with Vikram walking through Mail, not with a slogan.

Do Mail once by hand. one Mail step Vikram can write from memory. Change one input. Say the new result out loud.

Without Mail, lab hour gets messy and Vikram walking through Mail is hard to trust.

Use Mail when Vikram walking through Mail must stay clear. If a simpler PHP step works, use that instead.

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

Place Mail next to nearby PHP work — one Mail step Vikram can write from memory is the link.

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

Exam tip

For Mail: definition + lab hour + one failure.

Example

<?php
// Mail
$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";
}

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

Short notes

DefMail — Vikram uses it for Vikram walking through Mail in lab hour.
RuleMail → one Mail step Vikram can write from memory.
RememberMail + a .php page (lab hour).
UseMail in lab hour (Vikram walking through Mail).
TrapMail — only reciting the name of Mail.
ExMail → Vikram walking through Mail.
