Yes. Certainly, I care whether they're written in a systems
programming language (C, C++), a good stable interpreted language
(Python, Perl), or somebody's favorite toy language with semantics
resembling a language best left on the dustheap of the eighties (Copy
on read? What were they thinking?).
I'd rather have an SSH server written in a garbage-collected language
with mandatory bounds checking, for example: on those machines which
aren't terminal servers, OpenSSH's has about ten times as much code as

Yes. PHP's not Ultimate Evil, it's just kind of chintzy:
* It's a special-purpose language, but used to write large
applications. General purpose languages tend to pick up more
mindshare, attract better programmers, and pick up more eyeballs
skimming for bugs. Their code's more maintainable, too.
* The language was never planned. PHP is still at the stage Perl was
with Perl 4: a bunch of Neat Features without any idea of what
happens when you use them all at once.
* Because of its niche, it picks up an unusually high proportion of
poor programmers. This doesn't affect any *particular* program -- I
use SquirrelMail myself, and love it -- it's just that "PHP" is as
much of a warning sign to me when looking at a programmer's resume
as seeing one published piece of software, an IRC client.
* It's very easy to use PHP insecurely. This is compounded by the PHP
engine's security record.
So what does this mean for you, as an ISP considering two
web-interface applications, one written in PHP, and the other in Perl
(say, with Mason)? You have reason to be more nervous about the machine
the PHP app is on, and you'll have to search more widely and examine
candidates more closely when finding maintenance programmers.
