PHP & MySQL: Unicode number add, subtract etc for any language

Hello Coders!

Recently a visitor from my country asked me how he can add Unicode numbers stored in MySQL database.  I was thinking that it is really a good question. Because you may store any number in any local language to your database and later you may try to add or delete them.

For example, in Bangla language an employee’s salary can be ২৪১৮৬ (which is 24186 in English) bucks and the coder may want to store it in a table under salary field. Another field can be bonus and it can be ২০০ (2000 in English). Now the coder may want to add them up anytime required. You know adding 24186 and 2000 is easy. But what the coder may do in case the values are stored in a local language?

The visitor asked me how he can use the MySQL sum() function in case the data are stored in Unicode format. Well. I do not think MySQL’s unicode will support the sum() function or even if there is one I do not know frankly speaking. So, I thought and developed an alternative solution.

Here is the alternative solution steps:

  1. I get the unicode numbers from the database
  2. Convert them to English number
  3. Sum them up or anything like substract, multiply or divide etc
  4. Convert the result to Unicode once again

Thus, it looks simple procedure. Right?

Before we start I would like to suggest you download the codes from the bottom link of the page and take a look. Because some code may not look as the original one for browser’s case sensitiveness. So, it is better to look at the original code from the download link below.

So,  I wrote a small class to handle the whole procedure and here goes the coding of my class:

If you are not using Bengali language, you need to configure the equivalent number values in convertToEnglishNumber and convertToBanglaNumber functions.

And here goes the page where I am executing the displayTotalPayment() function.

Now the final result looks like this:

Oh! One important thing. If you are coding for European number format, you need to do some modification to handle the comma (,) factor in the number in case required.

Thus, if you use this small tricky method, you can add, subtract,  multiply or divide any local numbers such as Russian, Chinese, Arabic, Spanish, German, Polish, Turkey, Hindi etc.

You can also download this small piece of code from here:

WordPress: How to add and link static or custom pages

When I was new to wordpress theme development, I faced a common problem that many others might have faced. That is adding or linking or integrating a static or custom page in your wordpress site. It is very possible that you may prefer to keep one of your page or file linked as the following:


Sometimes this kind of requirement arrive that you have no other option but to do it.

But you know this kind of link will not directly appear in your wordpress blog or site because of the unique linking structure of wordpress. Most probably you will get a 404 error i.e. file not found error. So, if you want to link directly, you need to follow a simple trick. This trick is simple, small and intereting.

If you want to add and link your custom or static pages, follow these steps and you will get smooth result:

Step One: Changing the header of the php file

In this article, we will add a php file products.php in our wordpress blog. So, please create your products.php file.  Now open you products.php file and add the following two lines at the top of the file and save your file.

Remember, these lines will be the topmost lines in your products.php file. OK? See below how I added.

Why are we adding these two lines? Because we are telling wordpress that this file will not use wordpress themes and we are going to link it in a different way. So, wordpress do not force to link in its usual way.

Step Two: Saving in the public_html or root folder

Now upload it in the wordpress installation directory so that it looks like:


Done? Great!

Step Three: Linking the products.php file in a usual way

Now in the code of any wordpress file where you want to link your products.php file, keep the html linking as usual or what we say relative linking. For example, in the contact us page, I am creating such a link in the body section:

And yes! We are done!
Test now if it works for you.

Thus, you can add any number of pages in your wordperss site. I do not know exactly when you may need to link this way. I had to do it time to time depending on the client’s project requirement.

Thus, you can also protect your pages from permalink (dot)htaccess in wordpress.
