Definitely PHP had way more impact on the dev side. RoR came much later.
But Perl held on for a little longer in sysadmin circles, even as PHP started taking over web sites. Perl was THE glue code for us ops folks. There's still quite a bit of perl out there too.
Python took over on the ops side rather than Ruby, but that came later still. It wasn't until config management & early DevOps started becoming main stream that Python was replacing perl at scale.
