PHP4: Constant inside a class

[nebulom]

This gives me PHP Parse error: syntax error, unexpected ';', expecting '(' in C:\Program Files\Apache Group\Apache2\htdocs\toolmon\_debug_tmp.php on line 15 having a code

class test {
  var $SOME_CONST = 10;
}

echo test::$SOME_CONST;

Can't I create a constant variable inside a class?

Thanks.
