strtok()

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

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

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

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

Viva — what is strtok()? Then show the smallest strtok example you can type. Then name the trap.

Exam tip

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

Example

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

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