similar_text()

similar_text() is simple if you keep it on paper. Sara uses it for a similar_text dry-run in lab hour.

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

similar_text() exists so Sara can keep a similar_text dry-run correct in lab hour.

Sara ships similar_text() in lab hour. That is the use case worth saying.

If a similar_text dry-run breaks under similar_text(), check skipping the failure case for similar_text first.

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

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

Exam tip

For similar_text(): definition + lab hour + one failure.

Example

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

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