html_entity_decode() is the opposite of
   htmlentities() in that it converts all HTML entities
   in the string to their applicable characters.

Parameters : 
 string - The input string. 
 flags - A bitmask of one or more of the following flags, which specify how to handle quotes and
       which document type to use. The default is ENT_COMPAT | ENT_HTML401.
       
Available flags constants


Constant Name
Description




ENT_COMPAT
Will convert double-quotes and leave single-quotes alone.


ENT_QUOTES

ENT_NOQUOTES

ENT_HTML401

            Handle code as HTML 4.01.
           


ENT_XML1

            Handle code as XML 1.
           


ENT_XHTML

            Handle code as XHTML.
           


ENT_HTML5

            Handle code as HTML 5. 
 encoding - An optional argument defining the encoding used when converting characters.
 

  If omitted, the default value of the encoding varies
  depending on the PHP version in use. In PHP 5.6 and later, the
  default_charset configuration
  option is used as the default value. PHP 5.4 and 5.5 will use
  UTF-8 as the default. Earlier versions of PHP use
  ISO-8859-1.
 

  Although this argument is technically optional, you are highly encouraged to
  specify the correct value for your code if you are using PHP 5.5 or earlier,
  or if your default_charset
  configuration option may be set incorrectly for the given input.
