There are a number of reasons for this, and only some of them are
unwarranted. Novice developers find the language's sometimes-complex
syntax intimidating, and its freewheeling "there's more than one way
to do it" attitude confusing. The special symbols and variables that
experienced Perl developers sprinkle liberally around their code (can
you say @_?), coupled with the intricacies of Perl variable scoping,
regular expressions, object-oriented programming and modules, can
leave them bewildered and weak at the knees, and the language's terse
error messages only serve to increase their frustration when things
go wrong.

Using
perl to connect to remote hosts via telnet
Suppose you needed to open a connection to a remote host from within
your perl program. One thing you would probably think of doing at
first is the following:
open TELNET "|telnet $hostname"; print TELNET "$username "; print
TELNET "$password "; ... Unfortunately, if you try this, you'll find
it doesn't work. The telnet program connects to the remote host but
it completely ignores any commands you pipe to it. That's because
the telnet program reads it input only from the terminal and not from
standard input.

Using
Perl code from PHP
PHP and Perl are two very popular Web programming languages. They
both have many libraries and extensions that can simplify the process
of development, but often you can find a Perl library you want, and
not the corresponding library in PHP. (Perl is older then PHP, so
naturally it has a larger selection of libraries and extensions.)
This was the main reason that the Perl extension for PHP was written.
Many large projects use both PHP and Perl, with some subsystems implemented
in PHP, and others in Perl. Often these subsystems need to communicate
with each other, and some Perl modules - such as PHP::Include and
PHP::Session - have been implemented to achieve this (see
http://www.cpan.org/modules/by-module/PHP/ for more information).
However, although they allow PHP session files to be read, PHP variables
to be serialized and simple PHP code to be executed from within Perl,
there is no real communication between the two interpreters.
