Question

I’m trying to call a function from within a heredoc, and I read in the manual (example #2) that it is possible. However, I get the following error: Notice: Undefined property: TIME::$since on line 13.

1   <?php class TIME {
2       var $month;
3       var $year;
4       public function since($y) {
5           $this->$month = (date("F"));
6           $this->$year = (date("Y")-$y);
7           return "(since $month of $year)";
8           // return "(since date('F') of {date('Y')-$y})";
9       }
10  }
11  $time = new TIME;
12  echo <<<EOF
13      {$time->since{1}};
14  EOF; ?>

What I need to do is pass 1 as an integer to the function since() and return a string like (since January of 2011).

You have a lot of errors in your code. $this->$month and $this->$year must be $this->month and $this->year in your case, return "(since $month of $year)";, I think, must be return "(since {$this->month} of {$this->year})";, {$time->since{1}}; may be {$time->since(1)};, and, finally, EOF; ?> – ending PHP tag must be on newline when closing heredoc:

EOF;
?>

P.S. Why are you using old, PHP4-style properties declaration?
