log()

If you can teach log() using Sara walking through log, you know it. If you only know the heading, you don’t.

log() order — meaning → one log step Sara can write from memory → one limit. Dumping ten features helps nobody.

Without log(), a campus project gets messy and Sara walking through log is hard to trust.

log() shows up in a campus project. Name Sara walking through log, not “a real-world scenario”.

log() miss — copy-pasting log without a dry-run. Fix it before you talk about advanced PHP.

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

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

Exam tip

Say log() in one breath, then one log step Sara can write from memory, then copy-pasting log without a dry-run.

Example

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

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

Short notes

Deflog() — Sara uses it for Sara walking through log in a campus project.
Rulelog() → one log step Sara can write from memory.
Rememberlog() + Apache/Nginx (a campus project).
Uselog() in a campus project (Sara walking through log).
Traplog() — copy-pasting log without a dry-run.
Exlog() → Sara walking through log.
