How can text within an <h1> tag be passed through a form in PHP?

To pass text within an <h1> tag through a form in PHP, you can use the $_POST superglobal to retrieve the value of the <h1> tag from the form submission. Make sure to properly sanitize and validate the input to prevent any security vulnerabilities. 

&lt;?php
if ($_SERVER[&quot;REQUEST_METHOD&quot;] == &quot;POST&quot;) {
    $h1_text = $_POST[&#039;h1_text&#039;];
    
    // Sanitize and validate $h1_text here
    
    echo &quot;&lt;h1&gt;&quot; . $h1_text . &quot;&lt;/h1&gt;&quot;;
}
?&gt;

&lt;form method=&quot;post&quot; action=&quot;&lt;?php echo $_SERVER[&#039;PHP_SELF&#039;]; ?&gt;&quot;&gt;
    &lt;input type=&quot;text&quot; name=&quot;h1_text&quot;&gt;
    &lt;input type=&quot;submit&quot; value=&quot;Submit&quot;&gt;
&lt;/form&gt;
