localeconv()

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

Keep localeconv() small. Zara should finish a localeconv dry-run in a few lines, not a 40-line dump.

Without localeconv(), a first job task gets messy and a localeconv dry-run is hard to trust.

localeconv() shows up in a first job task. Name a localeconv dry-run, not “a real-world scenario”.

localeconv() trap — skipping the failure case for localeconv. Zara loses marks for that every viva.

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

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

Exam tip

Say localeconv() in one breath, then one localeconv step Zara can write from memory, then skipping the failure case for localeconv.

Example

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

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

Short notes

Deflocaleconv() — Zara uses it for a localeconv dry-run in a first job task.
Rulelocaleconv() → one localeconv step Zara can write from memory.
Rememberlocaleconv() + the PHP runtime (a first job task).
Uselocaleconv() in a first job task (a localeconv dry-run).
Traplocaleconv() — skipping the failure case for localeconv.
Exlocaleconv() → a localeconv dry-run.
