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 '&lt;'
  • '>' (greater than) becomes '&gt;'

This could be used to prevent XSS attak for example .
