Continue

Continue sits in a small live site. Vikram’s job is a Continue dry-run. Write that first.

Keep Continue small. Vikram should finish a Continue dry-run in a few lines, not a 40-line dump.

Without Continue, a small live site gets messy and a Continue dry-run is hard to trust.

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

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

After Continue, Vikram should still remember skipping the failure case for Continue.

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

Exam tip

Board: a Continue dry-run. Dry-run Continue. Name the trap: skipping the failure case for Continue.

Example

<?php
// Continue
$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";
}

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

Short notes

DefContinue — Vikram uses it for a Continue dry-run in a small live site.
RuleContinue → one Continue step Vikram can write from memory.
RememberContinue + Apache/Nginx (a small live site).
UseContinue in a small live site (a Continue dry-run).
TrapContinue — skipping the failure case for Continue.
ExContinue → a Continue dry-run.
