FTP Introduction

FTP Introduction is simple if you keep it on paper. Amit uses it for a hello.php page in a college portal.

Do FTP Introduction once by hand. <?php echo 'Hi'; ?>. Change one input. Say the new result out loud.

Skip FTP Introduction and calling PHP a database shows up in a college portal.

Use FTP Introduction when a hello.php page must stay clear. If a simpler PHP step works, use that instead.

If a hello.php page breaks under FTP Introduction, check calling PHP a database first.

FTP Introduction is not a lonely heading. Amit ties it to a hello.php page.

One breath for FTP Introduction, then a hello.php page, then calling PHP a database. Sit down.

Exam tip

Board: a hello.php page. Dry-run FTP Introduction. Name the trap: calling PHP a database.

Example

<?php
// FTP Introduction
$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";
}

FTP Introduction: scores array, print avg, then high marks. Say the output.
