I don't understand what your reply has to do with the original question of finding out whether a string is an HTML entity and my reply on how to detect whether a string is an HTML entity.

    For example : If the string contain $a= &foo foo When I encode it using the function encode_entities($a); The   should not be encoded. So the final output after encoding should be &foo foo Now the output is &foo foo. So I wanted to check it the string is HTML entity?

      I don't get your problem. Maybe if you posted real code instead of a mishmash of unencoded and encoded entities outside of <code> tags, it would be clearer. The following code works as I expect it and seems to do what you want:

      > perl -MHTML::Entities -le "print $HTML::Entities::VERSION; print enc
+ode_entities('&foo foo')"
1.35
&amp;foo foo

      [download]

      Which would indicate to me that &foo foo does not look like any valid HTML entity.
