New Comment:
I know that's a solution to cope with this. However code-wise it will
be cleaner to let only live the reader variable of a certain scope.

Your example would be handled by
$reader = new StreamReader($stream);
$reader->write('blahblahblah');
$reader = null; // $reader->__destruct() called
Objects and values are destroyed as soon as the last reference to them
goes away. Remove those references, destroy the object.
$start = microtime(true);
class foo{
private $name;
function __construct($name) {
$this->name = $name;
}
function __destruct() {
echo $this->name." Destroyed at
".(microtime(true)-$GLOBALS['start'])." seconds\n";
}
}
$t1 = new foo('t1');
$t2 = new foo('t2');
$t3 = new foo('t3');
echo "Set \$t1 to null at ".(microtime(true)-$start)." seconds\n";
$t1 = null;
echo "Sleep 5 seconds\n";
sleep(5);
echo "Replace \$t2 with \$t3 at ".(microtime(true)-$start)."
seconds\n";
$t2 = $t3;
echo "Sleep 5 seconds\n";
sleep(5);

Description:
------------
An implementation like C# (
http://www.coderjournal.com/2007/02/proper-use-idisposable/ ) would be
appreciated:
using(StreamReader reader = new StreamReader(stream))
{
reader.write('blalblabab');
}
The class StreamReader implements an interface IDisposable, by
implementing this interface (creating a function in the class called;
Dispose) the user can use the statement `using` to control the disposal
of the object manually instead of waiting of the garbage collection of
PHP.
This would be usefull for controling database connections, socket
connections, simplexml?, etc.
