How can a <Textarea> be properly placed in PHP code to display HTML content?

To properly display HTML content within a <Textarea> in PHP, you need to use the htmlspecialchars() function to escape the HTML tags and prevent them from being interpreted as actual HTML. This ensures that the content is displayed as plain text within the <Textarea> element.

&lt;?php
$html_content = &quot;&lt;p&gt;This is some &lt;strong&gt;HTML&lt;/strong&gt; content.&lt;/p&gt;&quot;;
?&gt;
&lt;textarea&gt;&lt;?php echo htmlspecialchars($html_content); ?&gt;&lt;/textarea&gt;
