Answer 1

如果您指的是维基百科所称的东部阿拉伯语/标记数字,那么简单的替换操作就应该这样做.

$western_arabic = array('0','1','2','3','4','5','6','7','8','9');
$eastern_arabic = array('?','?','?','?','?','?','?','?','?','?');

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

Answer 2

定义

• 西方阿拉伯数字:"1234567890".
• 东部阿拉伯数字:"1234567890".

答案

我前段时间写了几个函数(gist.github.com).

演示(3v4l.org)

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

码

<?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('?', '?', '?', '?', '?', '?', '?', '?', '?', '?');
    $arabic_western = array('0', '1', '2', '3', '4', '5', '6', '7', '8', '9');
    return str_replace($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('?', '?', '?', '?', '?', '?', '?', '?', '?', '?');
    $arabic_western = array('0', '1', '2', '3', '4', '5', '6', '7', '8', '9');
    return str_replace($arabic_eastern, $arabic_western, $str);
}
