Convert Persian/Arabic Numbers to English Numbers

convert Persian/Arabic numbers to English numbers

Because people in the Persian & Arabic region maybe use each other keyboard types, this is the complete solution to convert both types.

Based on @palladium answer.

function convert2english($string) {
    $newNumbers = range(0, 9);
    // 1. Persian HTML decimal
    $persianDecimal = array('۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹');
    // 2. Arabic HTML decimal
    $arabicDecimal = array('٠', '١', '٢', '٣', '٤', '٥', '٦', '٧', '٨', '٩');
    // 3. Arabic Numeric
    $arabic = array('٠', '١', '٢', '٣', '٤', '٥', '٦', '٧', '٨', '٩');
    // 4. Persian Numeric
    $persian = array('۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹');

    $string =  str_replace($persianDecimal, $newNumbers, $string);
    $string =  str_replace($arabicDecimal, $newNumbers, $string);
    $string =  str_replace($arabic, $newNumbers, $string);
    return str_replace($persian, $newNumbers, $string);
}

How to convert Persian and Arabic digits of a string to English using JavaScript?

Use this simple function to convert your string

var
persianNumbers = [/۰/g, /۱/g, /۲/g, /۳/g, /۴/g, /۵/g, /۶/g, /۷/g, /۸/g, /۹/g],
arabicNumbers  = [/٠/g, /١/g, /٢/g, /٣/g, /٤/g, /٥/g, /٦/g, /٧/g, /٨/g, /٩/g],
fixNumbers = function (str)
{
  if(typeof str === 'string')
  {
    for(var i=0; i<10; i++)
    {
      str = str.replace(persianNumbers[i], i).replace(arabicNumbers[i], i);
    }
  }
  return str;
};

Be careful, in this code the persian numbers codepage are different with the arabian numbers.

Example

var mystr = 'Sample text ۱۱۱۵۱ and ٢٨٢٢';
mystr = fixNumbers(mystr);

Refrence

Convert Persian to English numbers issue

$arr2 seems to contain Persian digits and $arr1 seems to contain Arabic digits. It means ٠ in the first array isn't the same ۰ in the second array, although shapes are similar.

To ensure they are different you could run bin2hex():

foreach ($arr2 as $key => $value) {
   echo $key, ': ', bin2hex($value), ' - ', bin2hex($arr1[$key]), "\n";
}

Outputs:

0: dbb0 - d9a0
1: dbb1 - d9a1
2: dbb2 - d9a2
3: dbb3 - d9a3
4: dbb4 - d9a4
5: dbb5 - d9a5
6: dbb6 - d9a6
7: dbb7 - d9a7
8: dbb8 - d9a8
9: dbb9 - d9a9

      input = input.replaceAll(english[i], arabic[i]);
    }
    print("$input");
    return input;
  }
