Are there any potential issues or pitfalls to be aware of when using implode in PHP for HTML generation?

One potential issue when using implode in PHP for HTML generation is that it does not automatically escape special characters, which can lead to security vulnerabilities such as cross-site scripting (XSS) attacks. To mitigate this risk, it is important to properly escape the values before using implode to concatenate them into HTML output. 

// Example of properly escaping values before using implode for HTML generation
$values = ['<script>alert("XSS attack!")</script>', 'Hello', 'World'];
$escaped_values = array_map('htmlspecialchars', $values);
$html_output = '<ul><li>' . implode('</li><li>', $escaped_values) . '</li></ul>';
echo $html_output;
