How can one troubleshoot and debug issues related to character replacement and code interpretation in PHP forum posts containing bbCode and HTML code?

Issue: When posting content with bbCode and HTML code in a PHP forum, character replacement and code interpretation issues may arise. To troubleshoot and debug these issues, ensure that the content is properly sanitized and escaped before displaying it on the forum to prevent any unintended character replacements or code interpretation. PHP Code Snippet: 

// Sanitize and escape content before displaying it in a PHP forum
$content = $_POST['content']; // Assuming the content is submitted via a form

// Sanitize the content to prevent any malicious code
$sanitized_content = htmlspecialchars($content, ENT_QUOTES, 'UTF-8');

// Display the sanitized content in the forum post
echo $sanitized_content;
