Convert English Numbers to Persian

Question

I am using the following JavaScript to convert all the English numbers showing on my website to Persian.

I realize that there are several ways to go about this and I have looked online and tried a few, however, this script does what I want it to do and it was really easy to implement except I want the phone number and date in my footer to be excluded from the conversion and remain English.

Not sure how I go about this in my PHP/HTML page.

On the second note, when my site is loading for a couple of seconds the numbers appear in English and quickly convert to Persian. Just wondering if there was a way that I could reduce this delay?

Here is my code:

<script language="JavaScript" 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] }
);
}
</script>

<script type="text/javascript">
window.onload = replaceDigits
</script>

Answer 1

Here you are :)

function toFarsiNumber(n) {
    const farsiDigits = ['۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹'];

    return n
      .toString()
      .split('')
      .map(x => farsiDigits[x])
      .join('');
  }

Another version!

function toFarsiNumber(n) {
    const farsiDigits = ['۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹'];

    return n
        .toString()
        .replace(/\d/g, x => farsiDigits[x]);
}

Answer 2

Here is the PHP function :

function toPersianNum($number)
    {
        $number = str_replace("1","۱",$number);
        $number = str_replace("2","۲",$number);
        $number = str_replace("3","۳",$number);
        $number = str_replace("4","۴",$number);
        $number = str_replace("5","۵",$number);
        $number = str_replace("6","۶",$number);
        $number = str_replace("7","۷",$number);
        $number = str_replace("8","۸",$number);
        $number = str_replace("9","۹",$number);
        $number = str_replace("0","۰",$number);
        return $number;
    }

Using :

$fa_num = toPersianNum(1234); // It returns ۱۲۳۴
$fa_date = toPersianNum('2016/05/10'); // It returns ۲۰۱۶/۰۵/۱۰

JavaScript

And here is the JavaScript function :

function toPersianNum( num, dontTrim ) {

    var i = 0,

        dontTrim = dontTrim || false,

        num = dontTrim ? num.toString() : num.toString().trim(),
        len = num.length,

        res = '',
        pos,

        persianNumbers = typeof persianNumber == 'undefined' ?
            ['۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹'] :
            persianNumbers;

    for (; i < len; i++)
        if (( pos = persianNumbers[num.charAt(i)] ))
            res += pos;
        else
            res += num.charAt(i);

    return res;
}

Using :

var fa_num = toPersianNum(1234) // It returns ۱۲۳۴
var fa_date = toPersianNum('2016/05/10'); // It returns ۲۰۱۶/۰۵/۱۰

Be Happy :)

UPDATE

Here are toEnglishNum() as well.

PHP:

function toEnglishNum($number)
{
    $number = str_replace("۱","1",$number);
    $number = str_replace("۲","2",$number);
    $number = str_replace("۳","3",$number);
    $number = str_replace("۴","4",$number);
    $number = str_replace("۵","5",$number);
    $number = str_replace("۶","6",$number);
    $number = str_replace("۷","7",$number);
    $number = str_replace("۸","8",$number);
    $number = str_replace("۹","9",$number);
    $number = str_replace("۰","0",$number);
    return $number;
}

Javascript:

function toEnglishNum( num, dontTrim ) {
    var i = 0,
        j = 0,
        dontTrim = dontTrim || false,
        num = dontTrim ? num.toString() : num.toString().trim(),
        len = num.length,
        res = '',
        pos,
        persianNumbers = typeof persianNumber == 'undefined' ?
            [ '۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹' ] :
            persianNumbers;

    for ( ; i < len; i++ )
        if ( ~( pos = persianNumbers.indexOf( num.charAt( i ) ) ) )
            res += pos;
        else
            res += num.charAt( i );
    return res;
};

Good Luck
