time()

time() (function) is simple if you keep it on paper. Priya uses it for Priya walking through time function in a small live site.

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

Skip time() (function) and skipping the failure case for time function shows up in a small live site.

time() (function) shows up in a small live site. Name Priya walking through time function, not “a real-world scenario”.

time() (function) trap — skipping the failure case for time function. Priya loses marks for that every viva.

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

One breath for time() (function), then Priya walking through time function, then skipping the failure case for time function. Sit down.

Exam tip

Board: Priya walking through time function. Dry-run time() (function). Name the trap: skipping the failure case for time function.

Example

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

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

Short notes

Deftime() (function) — Priya uses it for Priya walking through time function in a small live site.
Ruletime() (function) → one time function step Priya can write from memory.
Remembertime() (function) + the PHP runtime (a small live site).
Usetime() (function) in a small live site (Priya walking through time function).
Traptime() (function) — skipping the failure case for time function.
Extime() (function) → Priya walking through time function.
