What is the relevance of the <title> element in PHP when setting a new tab title?

The <title> element in PHP is relevant when setting a new tab title because it allows you to dynamically change the title of a webpage based on certain conditions or variables. This is important for providing users with relevant and descriptive titles for each page they visit on a website. By using the <title> element in PHP, you can easily customize the title of each page without having to manually change it in the HTML code.

&lt;?php
$title = &quot;Home Page&quot;; // Set default title
if (isset($_GET[&#039;page&#039;])) {
    $page = $_GET[&#039;page&#039;];
    if ($page == &#039;about&#039;) {
        $title = &quot;About Us&quot;;
    } elseif ($page == &#039;contact&#039;) {
        $title = &quot;Contact Us&quot;;
    }
}
?&gt;
&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;&lt;?php echo $title; ?&gt;&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;h1&gt;&lt;?php echo $title; ?&gt;&lt;/h1&gt;
    &lt;!-- Rest of your HTML content here --&gt;
&lt;/body&gt;
&lt;/html&gt;
