PHP 8.3 Introduction & Server Execution
Understand how PHP executes on servers, outputs HTML, and manages variables.
Why PHP Runs Over 77% of the Web
PHP is a server-side scripting language designed specifically for the web. When a browser requests a .php file, the server executes the PHP code, generates pure HTML, and sends only the HTML back to the user.
PHP Example • Chapter 01
<?php
// PHP 8.3 Server-Side Execution
$institute = "WeBotApp Academy Guwahati";
$established = 2009;
$currentYear = 2026;
$experience = $currentYear - $established;
$isVerified = true;
echo "<h2>WeBotApp Academy PHP Engine</h2>";
echo "<p>Institute: <strong>$institute</strong></p>";
echo "<p>Years of Operation: <strong>$experience Years</strong> in Assam</p>";
echo "<p>Verified Institute Status: " . ($isVerified ? "100% Certified" : "Pending") . "</p>";
