1. Fixed syntax in code formatting
2. Removed extra newline after the opening PHP tag.
3. Fixed array syntax issues
4. Updated htmlentities flags to ENT_QUOTES
Adding ENT_QUOTES to htmlentities enhances security by converting both single and double quotes to HTML entities, preventing potential security issues related to character encoding.
5. Replaced sizeof() with count().
This change is due to the deprecation of sizeof(), and it's recommended to use count() instead. Both functions essentially do the same thing, but using count() is a more modern and preferred practice.
