oop - Can a PHP object instance know its name? -

if have code this:

class person {     $age;     $height;     $more_stuff_about_the_person;      function about() {         return /* can person's name? */;     } }  $john = new person(); $peter = new person();  print $john->about();  // print "john". print $peter->about(); // print "peter". 

is possible print person's name, stored variable name, method?

as it's not standard procedure, i'm guessing it's bad idea.

i've looked , can't find it.

no. objects can have multiple names, or no names. happen here:

$john = new person(); $richie = $john;      // $john , $richie both refer same object. print $richie->about(); 

or here:

function f($person) {     print $person->about(); }  f(new person()); 

if objects need know own names, need explicitly store names member variables (like $age , $height).
