Break

Break is a PHP topic. In plain words you use it for pass if marks >= 40 in result.php. Don’t start with a slogan — start with that picture.

Smallest example: if / foreach ($arr as $row). Type it, run it, and say what you see. If you can do that from memory, you know Break.

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

Trap — foreach by reference then reuse the variable. Fix that before you talk about advanced PHP.

Viva — what is Break? Then show if / foreach ($arr as $row). Then name the trap.

Exam tip

What is Break? Show this: if / foreach ($arr as $row). Trap: foreach by reference then reuse the variable.

Example

<?php
// Break
$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";
}

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

Short notes

DefBreak — pass if marks >= 40 in result.php.
Ruleif / foreach ($arr as $row)
Trapforeach by reference then reuse the variable
