If I am understanding the text correctly it is saying that
$f1 = f1();
$f2 = f2($f1);
$f3 = f3($f2);
is using more memory than
$f3 = f3(f2(f1()));
For me this doesn't make any sense. In the latter case PHP will also
create temporary variables to store the return values. There should be
no difference in memory consumption.
