I am using the folloing script:

#!/usr/bin/perl -w

%credit_form_fields_extra = (
      "Cash in advance" => "",
      "Send a check" => "",
      "Authorize for once" => "Bank Account|test",
      "Cash on delivery" => "",
      "By credit card" => "Card Type|Card Holder Name|Card Number|Exp Month|Exp Year"
);

print "Content-Type: text/html\015\012\015\012";

foreach (keys %credit_form_fields_extra) {
      if ($_ eq "Authorize for once") {
            my @test = split("|",$credit_form_fields_extra{$_});
                  
            foreach my $test (@test) {
                  print "a: $test<br>";
            }
      }
}

1;

I want to split the $credit_form_fields_extra{'Authorize for once'} to an array @test.
The loop:

foreach my $test (@test) {
print "a: $test<br>";
}

has to return:

a: Bank Account
a: test

But it returns:

a: B
a: a
a: n
a: k
a:
a: A
a: c
a: c
a: o
a: u
a: n
a: t
a: |
a: t
a: e
a: s
a: t

What am I doing wrong?

This works for me ...

#!/usr/bin/perl -w

%credit_form_fields_extra = (
     "Cash in advance" => "",
     "Send a check" => "",
     "Authorize for once" => "Bank Account|test",
     "Cash on delivery" => "",
     "By credit card" => "Card Type|Card Holder Name|Card Number|Exp Month|Exp Year"
);

print "Content-Type: text/html\015\012\015\012";

foreach (keys %credit_form_fields_extra) {
     if ($_ eq "Authorize for once") {
          my @test = split(/\|/,$credit_form_fields_extra{$_});
               
          foreach my $test (@test) {
               print "a: $test<br>";
          }
     }
}

What I changed is the pattern where you want to split: instead of "|" , you should write /\|/ because "|" is  a meta-character.
I changed:
my @test = split("|",$credit_form_fields_extra{$_});
in:
my @test = split(/\|/,$credit_form_fields_extra{$_});

this gave as ouput [!! if you add "\n" in print -> print "a: $test<br>\n";  :
a: Bank Account<br>
a: test<br>

I assume you also want to have a new line when you add <br> to print?  
In perl, you will have to add "\n" instead of "<br>"



#!/usr/bin/perl -w

%credit_form_fields_extra = (
     "Cash in advance" => "",
     "Send a check" => "",
     "Authorize for once" => "Bank Account|test",
     "Cash on delivery" => "",
     "By credit card" => "Card Type|Card Holder Name|Card Number|Exp Month|Exp Year"
);

print "Content-Type: text/html\015\012\015\012";

foreach (keys %credit_form_fields_extra) {
     if ($_ eq "Authorize for once") {
          my @test = split(/\|/,$credit_form_fields_extra{$_});
               
          foreach my $test (@test) {
               print "a: $test\n";
          }
     }
}
