quotemeta()

quotemeta() is simple if you keep it on paper. Asha uses it for a quotemeta dry-run in a small live site.

Do quotemeta() once by hand. one quotemeta step Asha can write from memory. Change one input. Say the new result out loud.

quotemeta() exists so Asha can keep a quotemeta dry-run correct in a small live site.

Asha ships quotemeta() in a small live site. That is the use case worth saying.

Don’t do this with quotemeta() — copy-pasting quotemeta without a dry-run. Interviewers spot it in ten seconds.

After quotemeta(), Asha should still remember copy-pasting quotemeta without a dry-run.

One breath for quotemeta(), then a quotemeta dry-run, then copy-pasting quotemeta without a dry-run. Sit down.

Exam tip

For quotemeta(): definition + a small live site + one failure.

Example

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

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

Short notes

Defquotemeta() — Asha uses it for a quotemeta dry-run in a small live site.
Rulequotemeta() → one quotemeta step Asha can write from memory.
Rememberquotemeta() + a .php page (a small live site).
Usequotemeta() in a small live site (a quotemeta dry-run).
Trapquotemeta() — copy-pasting quotemeta without a dry-run.
Exquotemeta() → a quotemeta dry-run.
