As requested, here is a simple function that takes 4 arguments ($arg0-3)
and utilizes the php mail() function. I added the headers for an example
of how easy it is to utilize plPHP in PostrgreSQL.


CREATE OR REPLACE FUNCTION phpmail(text,text,text,text) RETURNS integer AS '
   # Argument list
   $email_address = $arg0;
   $email_from = $arg1;
   $subject = $arg2;
   $body = $arg3;


   #
   # ..Typically, you would validate arguments here


   # Build email headers
   $headers  =  "From: $email_from\r\n";
   $headers .= "Reply-To: $email_from\r\n";
   $headers .= "X-Mailer: plPHP";


   # Send email
   if (mail($email_address, $subject, $body, $headers)) {
     return 1;
   }
   else {
     return 0;
   }


' LANGUAGE 'plphp';
