Your array code is assuming that @array contains an array where each element is one letter from the string, which is not what it contains. You can make it contain that by using @array = split( '', "PERLPERLPEBLPEBLPERL" ); or you can just understand that you are dealing with a string, not an array, and take a different approach, such as...

my $string = "PERLPERLPEBLPEBLPERL";
my @answer = ( $string =~ m/(.{4})/g );
print "@answer\n";
