How can PHP developers efficiently troubleshoot errors related to displaying HTML content using <Textarea>?

To troubleshoot errors related to displaying HTML content using <Textarea>, PHP developers can check for any syntax errors or missing closing tags in the HTML content being displayed. They can also use the htmlentities() function to encode special characters in the content to prevent any parsing issues. Additionally, developers can use the htmlspecialchars() function to escape HTML entities in the content to ensure it is displayed correctly within the <Textarea> element. 

&lt;?php
// Sample HTML content to be displayed in &lt;Textarea&gt;
$html_content = &quot;&lt;p&gt;This is some &lt;strong&gt;HTML&lt;/strong&gt; content.&lt;/p&gt;&quot;;

// Encoding special characters in the HTML content
$encoded_content = htmlentities($html_content);

// Escaping HTML entities in the content
$escaped_content = htmlspecialchars($encoded_content);

// Displaying the content within a &lt;Textarea&gt; element
echo &quot;&lt;textarea&gt;&quot; . $escaped_content . &quot;&lt;/textarea&gt;&quot;;
?&gt;
