I am using checkdnsrr() to validate a post of an email address.  How can the
call be if'd by determining if it is an Unix system (or Windows system) so
an error won't pop up if it is a Windows system?

Re: checkdnsrr()


if( function_exists( 'checkdnsrr' ) )
      // not defined: probably Windows...

  somebody else suggested check_function_exists, which is an excellent
solution.  You can also look in $_SYSTEM['OS'].  If it is set and to
Windows_NT or something, then you are likely on a windows system.  Most
Unix-like operating systems will set $_SYSETM['OSTYPE'].

  If you look at , you will see in the user
comments at the bottom many solutions to the lack of a Windows version of
this function.  Check it out.


I am not an ANGRY man.  Remove the rage from my email to reply.
