This incorporates a bit from the others and a bit of my own. :) Normaly I would shove the prompt into a sub of its own and use it as the condition for the while loop, but here i went with the simpler way! I came from C too although I started with ++ so I had streams for input output instead of printf.

use strict;
use warnings;

my @phrases = ();
my $i = 1;
print "Please enter phrase number " . $i++  . " (or 'stop'): ";
while (<STDIN>) {
   chomp;
   last if /^stop$/;   #only if they put just the word stop
   print "Please enter phrase number " . $i++  . " (or 'stop'): ";
   push @phrases, $_;
}

printphrases(@phrases);
sub printphrases {
    my $i = 1;
    print $i++ . ") $_\n" foreach @_;
}

__DATA__
C:\test>perl input.pl
