Joko WandiroJoko Wandiro 1,9371 gold badge17 silver badges27 bronze badges You probably want to use some Unicode character encoding, for example UTF-8, and htmlspecialchars. Because there isn't any need to generate "HTML entities" for "all [the] applicable characters" (that is what htmlentities does according to the documentation) if it's already in your character set.

ciccic 7,1483 gold badges23 silver badges34 bronze badges The differences between htmlspecialchars() and htmlentities() is very small. Lets see some examples:
htmlspecialchars(string $string) takes multiple arguments where as the first argument is a string and all other arguments (certain flags, certain encodings etc. ) are optional. htmlspecialchars converts special characters in the string to HTML entities. For example if you have < br > in your string, htmlspecialchars will convert it into < b >. Whereas characters like µ † etc. have no special significance in HTML. So they will be not converted to HTML entities by htmlspecialchars function as shown in the below example.
htmlentities ( string $string) is very similar to htmlspecialchars and takes multiple arguments where as the first argument is a string and all other arguments are optional (certain flags, certain encodings etc.). Unlike htmlspecialchars, htmlentities converts not only special characters in the string to HTML entities but all applicable characters to HTML entities. answered Oct 6, 2018 at 11:08
