Best Practices

Best Practices is a PHP topic. In plain words you use it for a short Best Practices example in a college portal page. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Best Practices example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Best Practices.

From the example next to this theory — Best Practices: scores array, print avg, then high marks.

Trap — only saying “Best Practices” with no example. Fix that before you talk about advanced PHP.

Viva — what is Best Practices? Then show the smallest Best Practices example you can type. Then name the trap.

Exam tip

What is Best Practices? Show this: the smallest Best Practices example you can type. Trap: only saying “Best Practices” with no example.

Example

<?php
// Best Practices
$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";
}

Best Practices: scores array, print avg, then high marks. Say the output.
