date()

Amit only reaches for date() (function) when Amit walking through date function has to stay correct in a viva board.

Keep date() (function) small. Amit should finish Amit walking through date function in a few lines, not a 40-line dump.

date() (function) exists so Amit can keep Amit walking through date function correct in a viva board.

date() (function) shows up in a viva board. Name Amit walking through date function, not “a real-world scenario”.

If Amit walking through date function breaks under date() (function), check copy-pasting date function without a dry-run first.

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

Viva for date() (function): what it is → one date function step Amit can write from memory → the mistake (copy-pasting date function without a dry-run).

Exam tip

Board: Amit walking through date function. Dry-run date() (function). Name the trap: copy-pasting date function without a dry-run.

Example

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

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

Short notes

Defdate() (function) — Amit uses it for Amit walking through date function in a viva board.
Ruledate() (function) → one date function step Amit can write from memory.
Rememberdate() (function) + a .php page (a viva board).
Usedate() (function) in a viva board (Amit walking through date function).
Trapdate() (function) — copy-pasting date function without a dry-run.
Exdate() (function) → Amit walking through date function.
