How to destroy an object?

Question

As far as I know (which is very little) , there are two ways, given:

$var = new object()

Then:

// Method 1: Set to null
$va         


        

Answer 1

This is a simple prove that you cannot destroy an object, you can only destroy a link to it.

$var = (object)['a'=>1];
$var2 = $var;
$var2->a = 2;
unset($var2);
echo $var->a;

returns

2
