simulating perl's range handling

[Anon]

Hi guys,
Recoding some perl as PHP. Can anyone suggest the best way to write write the following perl code in PHP:

for my $i ( $a..$b, c$..d$, e$..$f) { ... }

The best I have come up with is:

foreach ( ( array_merge ( range($a, $b), range($c, $d), ... ) ) as $i ) { ... }

Is there a better way?

Thx in advance,
Scott
