Break

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

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

Break exists so Dev can keep a Break dry-run correct in a campus project.

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

Don’t do this with Break — skipping the failure case for Break. Interviewers spot it in ten seconds.

After Break, Dev should still remember skipping the failure case for Break.

One breath for Break, then a Break dry-run, then skipping the failure case for Break. Sit down.

Exam tip

Say Break in one breath, then one Break step Dev can write from memory, then skipping the failure case for Break.

Example

<?php
// Break
$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";
}

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

Short notes

DefBreak — Dev uses it for a Break dry-run in a campus project.
RuleBreak → one Break step Dev can write from memory.
RememberBreak + the PHP runtime (a campus project).
UseBreak in a campus project (a Break dry-run).
TrapBreak — skipping the failure case for Break.
ExBreak → a Break dry-run.
