So you're mainly testing I/O rather than the language: which depends on the
commands that are used for output in the language, how they are implemented,
how the console is driven, the console implementation code, the kind of
display, etc.

Changing your tests a little so that the loops increment a variable, and
putting the output at the end, makes PHP twice as fast as Perl (on the same
setup which had PHP seven times slower than Perl using your tests.) Eg:

$a=0;
for ($count = 10000000; $count >= 1; $count--) {
                $a=$a+1;
etc.

Still a lousy benchmark, but at least it avoids I/O which is highly 
misleading.
