ucfirst()

ucfirst() is simple if you keep it on paper. Sara uses it for ucfirst on Sara's board in a campus project.

Keep ucfirst() small. Sara should finish ucfirst on Sara's board in a few lines, not a 40-line dump.

Skip ucfirst() and copy-pasting ucfirst without a dry-run shows up in a campus project.

Use ucfirst() when ucfirst on Sara's board must stay clear. If a simpler PHP step works, use that instead.

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

ucfirst() is not a lonely heading. Sara ties it to ucfirst on Sara's board.

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

Exam tip

Board: ucfirst on Sara's board. Dry-run ucfirst(). Name the trap: copy-pasting ucfirst without a dry-run.

Example

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

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

Short notes

Defucfirst() — Sara uses it for ucfirst on Sara's board in a campus project.
Ruleucfirst() → one ucfirst step Sara can write from memory.
Rememberucfirst() + the PHP runtime (a campus project).
Useucfirst() in a campus project (ucfirst on Sara's board).
Trapucfirst() — copy-pasting ucfirst without a dry-run.
Exucfirst() → ucfirst on Sara's board.
