wordwrap()

Sara only reaches for wordwrap() when Sara walking through wordwrap has to stay correct in a viva board.

wordwrap() on the board: one wordwrap step Sara can write from memory. Then say what Sara walking through wordwrap looks like after.

Without wordwrap(), a viva board gets messy and Sara walking through wordwrap is hard to trust.

Use wordwrap() when Sara walking through wordwrap must stay clear. If a simpler PHP step works, use that instead.

Don’t do this with wordwrap() — only reciting the name of wordwrap. Interviewers spot it in ten seconds.

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

Close wordwrap() with: “If I skip it, Sara walking through wordwrap goes wrong like this: only reciting the name of wordwrap.”

Exam tip

Say wordwrap() in one breath, then one wordwrap step Sara can write from memory, then only reciting the name of wordwrap.

Example

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

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

Short notes

Defwordwrap() — Sara uses it for Sara walking through wordwrap in a viva board.
Rulewordwrap() → one wordwrap step Sara can write from memory.
Rememberwordwrap() + a .php page (a viva board).
Usewordwrap() in a viva board (Sara walking through wordwrap).
Trapwordwrap() — only reciting the name of wordwrap.
Exwordwrap() → Sara walking through wordwrap.
