sha1_file()

sha1_file() is a PHP topic. In plain words you use it for a short sha1_file example in a college portal page. Don’t start with a slogan — start with that picture.

Smallest example: the smallest sha1_file example you can type. Type it, run it, and say what you see. If you can do that from memory, you know sha1_file().

From the example next to this theory — sha1_file(): scores array, print avg, then high marks.

Trap — only saying “sha1_file” with no example. Fix that before you talk about advanced PHP.

Viva — what is sha1_file()? Then show the smallest sha1_file example you can type. Then name the trap.

Exam tip

What is sha1_file()? Show this: the smallest sha1_file example you can type. Trap: only saying “sha1_file” with no example.

Example

<?php
// sha1_file()
$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";
}

sha1_file(): scores array, print avg, then high marks. Say the output.
