What is PHP

PHP (what is) is simple if you keep it on paper. Isha uses it for a hello.php page in a college portal.

PHP (what is) on the board — <?php echo 'Hi'; ?>. Then say what a hello.php page looks like after.

Skip PHP (what is) and calling PHP a database shows up in a college portal.

PHP (what is) shows up in a college portal. Name a hello.php page, not “a real-world scenario”.

If a hello.php page breaks under PHP (what is), check calling PHP a database first.

PHP (what is) is not a lonely heading. Isha ties it to a hello.php page.

Viva for PHP (what is) — what it is → <?php echo 'Hi'; ?> → the mistake (calling PHP a database).

Exam tip

Say PHP (what is) in one breath, then <?php echo 'Hi'; ?>, then calling PHP a database.

Example

<?php
// What is PHP
$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";
}

What is PHP: scores array, print avg, then high marks. Say the output.

Short notes

DefPHP (what is) — Isha uses it for a hello.php page in a college portal.
RulePHP (what is) → <?php echo 'Hi'; ?>.
RememberPHP (what is) + Apache/Nginx (a college portal).
UsePHP (what is) in a college portal (a hello.php page).
TrapPHP (what is) — calling PHP a database.
ExPHP (what is) → a hello.php page.
