About HTML Encoding
HTML encoding is the process of converting special characters into HTML entities. This is essential for displaying characters that have special meaning in HTML (like < and >) and for preventing Cross-Site Scripting (XSS) attacks.
Security Benefits
Always encode user input before displaying it on a web page. This prevents malicious scripts from being executed. For example, if a user enters <script>alert('XSS')</script>, encoding converts it to safe text that displays literally instead of executing.
