Open File

Ananya only reaches for Open File when Open File on Ananya's board has to stay correct in lab hour.

Open File on the board: one Open File step Ananya can write from memory. Then say what Open File on Ananya's board looks like after.

Open File exists so Ananya can keep Open File on Ananya's board correct in lab hour.

Open File shows up in lab hour. Name Open File on Ananya's board, not “a real-world scenario”.

Open File miss — copy-pasting Open File without a dry-run. Fix it before you talk about advanced PHP.

Place Open File next to nearby PHP work — one Open File step Ananya can write from memory is the link.

Close Open File with: “If I skip it, Open File on Ananya's board goes wrong like this: copy-pasting Open File without a dry-run.”

Exam tip

Say Open File in one breath, then one Open File step Ananya can write from memory, then copy-pasting Open File without a dry-run.

Example

<?php
// Open File
$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";
}

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

Short notes

DefOpen File — Ananya uses it for Open File on Ananya's board in lab hour.
RuleOpen File → one Open File step Ananya can write from memory.
RememberOpen File + the PHP runtime (lab hour).
UseOpen File in lab hour (Open File on Ananya's board).
