Composer Autoload

If you can teach Composer Autoload using a Composer Autoload dry-run, you know it. If you only know the heading, you don’t.

Keep Composer Autoload small. Ananya should finish a Composer Autoload dry-run in a few lines, not a 40-line dump.

Skip Composer Autoload and skipping the failure case for Composer Autoload shows up in a first job task.

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

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

After Composer Autoload, Ananya should still remember skipping the failure case for Composer Autoload.

Viva for Composer Autoload: what it is → one Composer Autoload step Ananya can write from memory → the mistake (skipping the failure case for Composer Autoload).

Exam tip

For Composer Autoload: definition + a first job task + one failure.

Example

<?php
// Composer Autoload
$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";
}

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