Tip
The 'ampersand' character (&) should always be encoded as '&' when used in HTML attributes or text.
Did You Know?
HTML5 supports over 2,000 named character references for various symbols and languages.
HTML entities are used to represent characters that have special meaning in HTML or those that cannot be easily typed on a keyboard. For instance, the less-than sign (<) is used to start a tag; to display it as text, you must use the entity <. Encoding replaces these characters with a specific sequence starting with an ampersand and ending with a semicolon, ensuring the browser renders them as literal text rather than code.
Best Practice
Always encode data at the point of output to the HTML document to maximize security and prevent XSS.
Q: Why should I encode HTML entities? A: It is critical for security to prevent Cross-Site Scripting (XSS) and ensures that reserved HTML characters are displayed correctly as text.
