Redirect

Don’t start Redirect with jargon. Start with a Redirect dry-run. That is the whole point.

Redirect on the board — one Redirect step Riya can write from memory. Then say what a Redirect dry-run looks like after.

Skip Redirect and copy-pasting Redirect without a dry-run shows up in a campus project.

Redirect shows up in a campus project. Name a Redirect dry-run, not “a real-world scenario”.

If a Redirect dry-run breaks under Redirect, check copy-pasting Redirect without a dry-run first.

After Redirect, Riya should still remember copy-pasting Redirect without a dry-run.

One breath for Redirect, then a Redirect dry-run, then copy-pasting Redirect without a dry-run. Sit down.

Exam tip

Board: a Redirect dry-run. Dry-run Redirect. Name the trap: copy-pasting Redirect without a dry-run.

Example

<?php
// Redirect
$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";
}

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

Short notes

DefRedirect — Riya uses it for a Redirect dry-run in a campus project.
RuleRedirect → one Redirect step Riya can write from memory.
RememberRedirect + Apache/Nginx (a campus project).
UseRedirect in a campus project (a Redirect dry-run).
TrapRedirect — copy-pasting Redirect without a dry-run.
ExRedirect → a Redirect dry-run.
