Skip strcmp() and only reciting the name of strcmp shows up in a viva board.

Amit ships strcmp() in a viva board. That is the use case worth saying.

strcmp() miss — only reciting the name of strcmp. Fix it before you talk about advanced PHP.

After strcmp(), Amit should still remember only reciting the name of strcmp.

One breath for strcmp(), then strcmp on Amit's board, then only reciting the name of strcmp. Sit down.

Exam tip

Board: strcmp on Amit's board. Dry-run strcmp(). Name the trap: only reciting the name of strcmp.

Example

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

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

Rememberstrcmp() + a .php page (a viva board).
