str_split()

If you can teach str_split() using str_split on Amit's board, you know it. If you only know the heading, you don’t.

str_split() on the board: one str_split step Amit can write from memory. Then say what str_split on Amit's board looks like after.

Without str_split(), a campus project gets messy and str_split on Amit's board is hard to trust.

Amit ships str_split() in a campus project. That is the use case worth saying.

str_split() trap — copy-pasting str_split without a dry-run. Amit loses marks for that every viva.

Place str_split() next to nearby PHP work — one str_split step Amit can write from memory is the link.

Close str_split() with: “If I skip it, str_split on Amit's board goes wrong like this: copy-pasting str_split without a dry-run.”

Exam tip

Say str_split() in one breath, then one str_split step Amit can write from memory, then copy-pasting str_split without a dry-run.

Example

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

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