Convert all applicable characters to HTML entities.

EX :

'"' (double quote) becomes '"' when ENT_NOQUOTES is not set.
"'" (single quote) becomes '&#;' (or ') only when ENT_QUOTES is set.
'<' (less than) becomes '<'
'>' (greater than) becomes '>'

This could be used to prevent XSS attak for example .
