CLI

Don’t start CLI with jargon. Start with Riya walking through CLI. That is the whole point.

For CLI, a .php page is in play. Don’t blame it until you have traced Riya walking through CLI.

Without CLI, lab hour gets messy and Riya walking through CLI is hard to trust.

Riya ships CLI in lab hour. That is the use case worth saying.

If Riya walking through CLI breaks under CLI, check skipping the failure case for CLI first.

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

Close CLI with — “If I skip it, Riya walking through CLI goes wrong like this: skipping the failure case for CLI.”

Exam tip

For CLI: definition + lab hour + one failure.

Example

<?php
// CLI
$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";
}

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

Short notes

DefCLI — Riya uses it for Riya walking through CLI in lab hour.
RuleCLI → one CLI step Riya can write from memory.
RememberCLI + a .php page (lab hour).
UseCLI in lab hour (Riya walking through CLI).
TrapCLI — skipping the failure case for CLI.
ExCLI → Riya walking through CLI.
