Control Statements

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

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

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

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

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

Exam tip

echo "avg=" . number_format($avg, 1) . "\n";
foreach ($scores as $s) {
  if ($s >= 80) echo "high: $s\n";
