Persian, Arabic and English digits

Use DigitConverter for display or to normalize a string before passing it to a numeric API. Conversion preserves leading zeros and non-digit text.

<?php

use Eram\Abzar\Digits\DigitConverter;

echo DigitConverter::toEnglish('۰۰۱٢'), "\n";
echo DigitConverter::toPersian('Version 1.2'), "\n";
echo DigitConverter::toArabic('۱۲3'), "\n";
echo DigitConverter::convertContent('<a href="page-5">Item 5</a><code>123</code>'), "\n";

0012
Version ۱.۲

<a href="page-5">Item ۵</a><code>123</code>

Each target method converts both other supported digit scripts. These methods return strings; they do not validate a number, strip grouping, convert decimal separators, or perform arithmetic. Use formatting for numeric display and validate before casting to an integer. Never cast identifiers with leading zeros.

convertContent() converts to Persian only. It leaves tags, attributes, entities, comments and script / style / pre / code / textarea content untouched. It uses a regex segmenter, not a sanitizer; plain toPersian() would also change digits in URLs and attributes.
