Convert English numbers to Arabic numerals

Question

How can i convert English numbers being retrieved from the database to Arabic numeral symbols in PHP.

EDIT: Here\'re some examples of what Arabic numerals look like.

Answer 1

I would suggest u to try using resource file for different language especially if the contents are known. Example: 2 file language files, 1 named language_EN, another language_AR where langauge_EN is to store the values in english, and language_AR for arabic.

so for instance u want store the number "1"

in langauge_EN, do something like this. number.one=1

then in langauge_AR, (pretend x is the number "1" in arabic, but I guess unicode is preferred) number.one=x

so after u retrieve from database and knowing that it is number, your raw result comes out to be "one".

so use number.+[result from database] to load from the langauage_AR This method is quite widely used in webpages which allow toggling of language. So at any time u need to convert back to english, just change back to language_EN. This works not only for number. Gd Luck

Answer 2

Simple solution with strtr:

strtr($str, ['٠','١','٢','٣','٤','٥','٦','٧','٨','٩']);

To convert from Eastern Arabic to Arabic:

strtr($str, array_flip(['٠','١','٢','٣','٤','٥','٦','٧','٨','٩']));

Answer 3

If you are referring to what Wikipedia calls eastern arabic / indic numerals, a simple replace operation should do.

$western_arabic = array('0','1','2','3','4','5','6','7','8','9');
$eastern_arabic = array('٠','١','٢','٣','٤','٥','٦','٧','٨','٩');

$str = str_replace($western_arabic, $eastern_arabic, $str);

Arabic Numbers:

function to_arabic_number($number)
{
    $number = str_replace("1","۱",$number);
    $number = str_replace("2","۲",$number);
    $number = str_replace("3","۳",$number);
    $number = str_replace("4","٤",$number);
    $number = str_replace("5","٥",$number);
    $number = str_replace("6","٦",$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;
}

Persian Numbers:

function to_persian_number($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;
}

• Eastern arabic numerals: "١٢٣٤٥٦٧٨٩٠".

The answer

I wrote a couple of functions (gist.github.com) a while back.

Demo (3v4l.org)

    echo arabic_w2e("1234567890"); // Outputs: ١٢٣٤٥٦٧٨٩٠
    echo arabic_e2w("١٢٣٤٥٦٧٨٩٠"); // Outputs: 1234567890

Code

<?php

/**
 * Converts numbers in string from western to eastern Arabic numerals.
 *
 * @param  string $str Arbitrary text
 * @return string Text with western Arabic numerals converted into eastern Arabic numerals.
 */
function arabic_w2e($str)
{
    $arabic_eastern = array('٠', '١', '٢', '٣', '٤', '٥', '٦', '٧', '٨', '٩');
    $arabic_western = array('0', '1', '2', '3', '4', '5', '6', '7', '8', '9');
    return str_replace($arabic_western, $arabic_eastern, $str);
}

/**
 * Converts numbers from eastern to western Arabic numerals.
 *
 * @param  string $str Arbitrary text
 * @return string Text with eastern Arabic numerals converted into western Arabic numerals.
 */
function arabic_e2w($str)
{
    $arabic_eastern = array('٠', '١', '٢', '٣', '٤', '٥', '٦', '٧', '٨', '٩');
    $arabic_western = array('0', '1', '2', '3', '4', '5', '6', '7', '8', '9');
    return str_replace($arabic_eastern, $arabic_western, $str);
}
