PHP - Php & Bank Wire Transfers

Hi,
Im developing a program and it contains bank details in some of the fields stored in the MySQL database.
As part of the upload, I need to find bank details and then mask them by replacing them with XXXXXX for security purposes.

An example of a field could be "TRANSFER 540021 61782457" and I need to replace to "TRANSFER XXXXXX XXXXX457"

Any ideas to the best possible method?

Maybe I would mask blocks of numbers (ie numbers in blocks of 6 or 9) to cover this...im not sure what the best possible way is.

Thanks!

Hi wondered if someone could help me i have this code:

if (isset($data['product_image'])) {
         foreach ($data['product_image'] as $image) {

         $image = $image.".jpg";
         $image = str_replace (" ", "", $image);
         
         $filename = '/home/purchase/public_html/fancydresscostumesonline.co.uk/image/'. $image;

         if (file_exists($filename)) {
         $this->db->query("INSERT INTO " . DB_PREFIX . "product_image SET product_id = '" . (int)$product_id . "', image = '" . $this->db->escape($image) . "'");   
         } else {
            $this->db->query("INSERT INTO " . DB_PREFIX . "product_image SET product_id = '" . (int)$product_id . "', image = 'no_image.jpg'");
         }
         
         }
      }

This part of the code adds a jpg at the end of the product_image additional images so in my csv the 10 columns which have additional numbers for example in my csv it has: say 00532 so this code adds 00532.jpg once imported the the next part which is the else statement no_image.jpg adds a no_image.jpg but instead of it inserting a no_image.jpg for all the blank cells i would like it to SKIP the blank cells for the additional images which is product_image so if no number in the cell it SKIPS it. but have no clue how to do it.

Hope someone can help

Hello,   I designed (not coded) a finance application for windows phone 8.1 and one of the features that would be ideal is to copy your login steps in order to access your bank account automatically. Yes this does not sound safe or sane. How do I convince app users to use it?    Anyway, I want this access. My rationale is that, the login information would be stored locally and if my phone was hacked then what's the loss in my login steps being hacked... they would probably be encrypted anyway but...    The goal is to be able to open up a clone browser (eg. within the app) and then every step that you take, enter url, login credentials, security questions, pages accessed... the clone browser remembers and then later on as part of the app's function, it would automatically update your balances. I mean I suppose you could come up with the formulas, cash advance fees, interest rates, etc... but at the same time this doesn't seem to be a fixed thing... eg. hard to keep track and get the exact cent amount... or maybe I'm just bad at math   Some things in mind bitmapping, key strokes, string search, number search...    Anyway scripting came to mind, not sure if php or python but    Any thoughts?
