From the above Xdebug output, we see that both the old and new array
element now point to a zval container whose "refcount" is
<literal>2</literal>. Of course,
there are now two zval containers, but they are the same one. The
elements now point to a zval container whose "refcount" is
<literal>2</literal>. Although Xdebug's output shows two zval containers
with value <literal>'life'</literal>, they are the same one. The
<function>xdebug_debug_zval</function> function does not show this, but
you could see this by also displaying the memory pointer. Removing an
element from the array is like removing a symbol from a scope. By doing
so, the "refcount" of a container that an array element points to is
decreased. Again, when the "refcount" reaches zero, the variable
you could see it by also displaying the memory pointer.
