how can i obtain name of the class instance from its inside

[sinasalek]

class TTest
{
function instance_name()
{
echo "instance name : $instance_name" ;
}
}

$test=new TTest();
$text->instance_name( );

result :
instance name : test

i searched the web, but i couldn't find any real way.
i just found some programming ways.
1.
$test=new TTest('test'); //'test' is name of instance
2.
$test=new TTest();
$test->instance_name= 'test';
3.
$instance='test ';
$$instance=new TTest($instance );

if need somthing like get_class but not for class name, for instance
name.
any idea will be appreciate.

How can an instance of an object have a name? What would it be the name
of?


Do you wish to find the name of the variable that "holds" the object?
What if you have more than one variable that points to the same object,
what would the name be then?

You can name the instances using a static variable. The simplest method
is incrementing the static variable(name variable ? ) on constructor,
so that you can have a different value on each instance. You can
implement a naming mechanism too, instead of justy implementing.
Hope it helps.

Re: how can i obtain name of the class instance from its inside

i found the solution by lilleman help, but i changed that from class to
function.

<?php
/**
* get name of object by its value, if its name does unique
*
* @param object $object
* @return string
*/
function get_instance_na me($object)
{
$instance = md5(serialize($ object));

foreach( $GLOBALS as $variable => $value )
if( md5(serialize($ value)) == $instance )
return $variable;
}

//--(End)-->example
class Foo
{
public function get_name()
{
return get_instance_na me($this);
}
}

$foo = new Foo;
echo $foo->get_name();
//--(End)-->example
?>
