How can one determine if a website is coded in PHP?

To determine if a website is coded in PHP, you can check the file extensions of the website's pages. PHP files typically have extensions like .php, .php4, .php5, or .phtml. Additionally, you can view the page source and look for PHP-specific code enclosed in <?php ?> tags. 

&lt;?php
// Check if a website is coded in PHP
$url = &quot;http://www.example.com&quot;;
$headers = get_headers($url, 1);

if (isset($headers[&#039;X-Powered-By&#039;]) &amp;&amp; strpos($headers[&#039;X-Powered-By&#039;], &#039;PHP&#039;) !== false) {
    echo &quot;This website is coded in PHP.&quot;;
} else {
    echo &quot;This website is not coded in PHP.&quot;;
}
?&gt;
