Perl is good and very useful. Its gots LOTS of other modules (CPAN) available that u can grab and tons of examples 2go play with.
Really depends on what u're background is.
If u're going 2b doing a lot of 'glue-ing' then its the bees-kness. It can be a little hard 2 start off with (until u get used 2 its syntax)
If u're gonna do more stuff e.g. web sites, larger stuff then I'd say go take a look at Ruby on Rails. It can do gluing stuff as well but not got the library that Perl has.
Php is good 2 but more weby language and not got a lot of (built-in) hooks that Perl has.
