How to replace entire numbers in a website to persian numbers via PHP?

Question

How to replace entire numbers in body or website html to persian numbers via PHP?
I want to replace all numbers in my website for all pages .

Code:

function ta_persian_num($string) {
  //arrays of persian and latin numbers
  $persian_num = array('۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹');
  $latin_num = range(0, 9);

  $string = str_replace($latin_num, $persian_num, $string);

  return $string;
}

My Code work for Client Side:

<script>
    $(document).ready(function(){
    persian={0:'۰',1:'۱',2:'۲',3:'۳',4:'۴',5:'۵',6:'۶',7:'۷',8:'۸',9:'۹'};
    function traverse(el){
        if(el.nodeType==3){
            var list=el.data.match(/[0-9]/g);
            if(list!=null && list.length!=0){
                for(var i=0;i<list.length;i++)
                    el.data=el.data.replace(list[i],persian[list[i]]);
            }
        }
        for(var i=0;i<el.childNodes.length;i++){
            traverse(el.childNodes[i]);
        }
    }
    traverse(document.body);
});
</script>

I'm new with PHP how should I use this function for all body numbers,I mean how to replace entire numbers in body automaticaly — Saeed Heidarizarei, Nov 12 '18 at 14:24
@SedricHeidarizarei what do you mean by body?! this function is so simple, just pass you string as a parameter, and it will replace the numbers and then return the string! — Mohammad, Nov 12 '18 at 14:27
Is there any server side way? for replacing all numbers with a short code in server? — Saeed Heidarizarei, Nov 12 '18 at 14:31
@SedricHeidarizarei It depends on the source of your "body" strings. If they are from multiple sources, you have a lot of work to do in php, so it's better to use something client-side. — Mohammad, Nov 12 '18 at 14:34
Thanks But I have Client side Solution, I need an example for server side. — Saeed Heidarizarei, Nov 12 '18 at 14:36
Maybe [output buffering](https://stackoverflow.com/questions/2832010/what-is-output-buffering) help you. Using it, you can get all printed content in variable and run your function on it. — Mohammad, Nov 12 '18 at 14:42
PHP doesn't know a `` tag. It just generates text and sends it to the client. — Lithilion, Nov 15 '18 at 11:58
Is bettter to do that with css or js? what should I do with this question? :D — Saeed Heidarizarei, Nov 15 '18 at 12:00
I think everybody told you already. Use JS. (Don't know what you wanna do with CSS though) — Lithilion, Nov 15 '18 at 12:17
@SedricHeidarizarei Do you use any PHP frameworks for a website? — Sergei Karpov, Nov 22 '18 at 09:42

You should better move this functionality to frontend end use javascript:

<script type="text/javascript">
var replaceDigits = function() {
    var map = ["&\#1776;","&\#1777;","&\#1778;","&\#1779;","&\#1780;", "&\#1781;","&\#1782;","&\#1783;","&\#1784;","&\#1785;"]
    document.body.innerHTML = document.body.innerHTML.replace(/\d(?=[^<>]*(<|$))/g, function($0) { return map[$0]});
}
window.onload = replaceDigits;
</script>

Ex: https://codepen.io/anon/pen/rQWGRd

or you can include this function in any your js file which is loaded on all pages.

And also your body tag should have a onload attribute like the following:

<body onload="replaceDigits()">

@SedricHeidarizarei So what happened to "Thanks But I have Client side Solution, I need an example for server side"? You were advised to use Javascript almost 30 minutes ago and you refused. What changed? – Patrick Q Nov 12 '18 at 14:58

✅ Solved My Problem with This way:

1: Use FontCreator 9 or 10 Program.
2: Open your font in FontCreator.
3: Goto Numbers tab.
4: Paste your RTL language numbers (Persian/Hebrew/Arabic) On english numbers.

Enjoy Without any F... Functions / Extra Processing.

Update:
It should also be replaced on Arabic too

Odd, but interesting solution. Please note that users who cannot download this font will get arabic numbers displayed. – Lithilion Nov 16 '18 at 08:05
@Lithilion Yes that's right, It should also be replaced on Arabic too, I updated the answer with a new Photo. – Saeed Heidarizarei Nov 16 '18 at 11:52

No, thats not the point. If someone cannot load your custom font, there is a fallback to a system font (i.e. Arial, Times New Roman,...) and these will have the "standart" numbers on these places – Lithilion Nov 16 '18 at 11:54
Yes True But This Solution works 99% for all users if you use all font formats(eot.woff.woff2 and ...), – Saeed Heidarizarei Nov 16 '18 at 12:01

The nicest way to do in PHP, is using regular expressions:

$string='salam 1 23 12';
$persian_num = array('۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹');
for($i=0;$i<10;$i++){
    $string = preg_replace("/$i/", $persian_num[$i], $string);
}
print($string);

Code above, replaces all English numbers with your specified characters in Persian.

If you really want to do this in PHP, you can concat all text/html output into the same variable and then echo it in the end. Between the the last concat and the echo you can call this function, in every .php page you echo output.

<?php
//Code...
$string = ta_persian_num($string);
echo $string;

Personally I would prefer JS for this question.

How to pass my page numbers from $string ? Can you write an example for index.php ? I mean something like this : ta_persian_num(document.body) – Saeed Heidarizarei Nov 12 '18 at 14:47
That's the thing. There is no `document.body` in PHP. You have to write all the output into `$string`or whatever you call it and then call this funtion. – Lithilion Nov 12 '18 at 14:51
This is not a good solution because I can't write all of my output into $string – Saeed Heidarizarei Nov 12 '18 at 15:01
