Re: instanceof / __CLASS__ question

Hi, I'm not sure I understand why you would use instanceof on $this. Try this code: <?php class a1 { } class a2 extends a1 { } echo new a1 instanceof a1; // true echo new a2 instanceof a1; // true ?> instanceof defines whether an object is or descends from a class (like is_a()). If you want to check whether $this is the Test class or a descendant class, the simplest way I know is if (get_class($this) == 'Test') otherwise, you could use reflection $z = new ReflectionClass($this); if ($z->getName() == 'Test') but that's a bit more cumbersome.

It's only a minor nuisance, but in order to use __CLASS__ with instanceof I have to assign __CLASS__ to a variable first. Should I bother submitting a bug report for this? Or am I perhaps missing something... <?php class Test { function checkObj2() {

    //workaround
    $class = __CLASS__;
    if ($this instanceof $class) {
      return TRUE;
    } else {
      return FALSE;
    }

} function checkObj() {

    // this causes a parsing error
    // return ($this instanceof __CLASS__);

} } $t = new Test(); echo $t->checkObj2() ? 'TRUE' : 'FALSE'; echo $t->checkObj(); // can't even test it ?>
