I've been searching a lot, but can't really find what i exactly need.

Im running a shop-online using XAMPP, and what i want is send emails to the customers with their order but using a specific function.

What this fuction does, is to hide some characters (for security purpose) on the email sent to customers. So i've made the function (looking on internet), but i want to test it now.

This is my function (if it's wrong, i'd really appreciate some help):

<?php
 function xtc_hide_iban ($iban) {

$length = strlen($iban);
$lchars = substr($iban,0 ,5);
$rchars = substr($iban, -5);
$iban_hidden = $lchars.str_repeat('*',$length-10).$rchars;
return $iban_hidden;

}
?>

I think it's pretty obvious what i try to do, but i will still explain it:

Get the $iban from customers, and show only the first and last 5 characters when the email is sent e.G

Your IBAN is 'DE123************56789'

So, for now i can send emails from Mercury mail server to 'root@localhost',account i made on thunderbird, (it's the only account that worked for me, because any other with the same server, like 'anyname@localhost' didn't work or couldn't be created, and those who were create with imap before couldn't access to the inbox "could not connected to server, connection refuse", anyway this works with POP3)

Following what i looked before, is that somehow and somewhere i can put a *.php on Mercury folder so i will get a template of how to send the mails (headers, subject,body,etc).

My main question is how and where to do that? make a test php file to make sure my code is doing what i want to do

Thanks in advance

    `$lchars = $iban.substr(0 ,5);` and `$rchars = $iban.substr(-5);` aren't going to work. It should be `$lchars = substr($iban, 0, 5);` – Lost F. Apr 10 '15 at 10:25
  • Thanks @RobinRijkeboer, i had my code as you write it before, but changed after seen some other examples on internet, so i got confused. Let me know if you see any other mistake – Nighthunter22 Apr 10 '15 at 10:35
