getdate()

If you can teach getdate() (function) using a getdate function dry-run, you know it. If you only know the heading, you don’t.

getdate() (function) on the board: one getdate function step Sara can write from memory. Then say what a getdate function dry-run looks like after.

Skip getdate() (function) and skipping the failure case for getdate function shows up in a viva board.

Use getdate() (function) when a getdate function dry-run must stay clear. If a simpler PHP step works, use that instead.

getdate() (function) miss — skipping the failure case for getdate function. Fix it before you talk about advanced PHP.

Place getdate() (function) next to nearby PHP work — one getdate function step Sara can write from memory is the link.

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

Exam tip

For getdate() (function): definition + a viva board + one failure.

Example

<?php
// getdate()
$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";
}

getdate(): scores array, print avg, then high marks. Say the output.

Short notes

Defgetdate() (function) — Sara uses it for a getdate function dry-run in a viva board.
Rulegetdate() (function) → one getdate function step Sara can write from memory.
Remembergetdate() (function) + the PHP runtime (a viva board).
Usegetdate() (function) in a viva board (a getdate function dry-run).
