Only thing I get is this output:
Notice: Undefined variable: var in /opt/www/t.php on line 4

And no leak. How about providing us a bit more information and a script that does not have any errors/notices in it? Your configure line would be nice to know. And what extensions (if any) you load in php.ini..

you probably need excute it for a while (5 min maybe!!)
and  $var maybe need to put some data inside
at client browser, every things looks fine
i didn't get any error but memory leak
it seem call sapi or something .....

How about you first upgrade your apache to something more recent. 
And then you really need to provide the configure line you used to configure PHP. Also: using "register_globals = On" is something you really shouldn't be doing..
