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);
}

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);
