$input_html = "In this example, the `$input_html` variable contains a potentially harmful script tag that could execute arbitrary code if not sanitized. The `safe_html` function is used to remove the script tag and any other dangerous attributes or tags. This function is typically implemented as part of a larger library or package focused on web security or HTML manipulation. Some possible examples of packages that might include a safe_html function are: - HTMLPurifier: a library for HTML filtering and purification that includes XSS protection features. - Symfony Security: a PHP framework that includes a variety of security-related components, including an HTML sanitizer. - PHP-ESAPI: an implementation of the OWASP Enterprise Security API that includes XSS filters and other security features.This is a safe paragraph.
