Requirements

PHP 8.1 or newer. Tested on PHP 8.1, 8.2, 8.3, 8.4, and 8.5.

Description

MbWrapper is intended for use wherever mb_* or iconv_* is used. It scans supported charsets returned by mb_list_encodings(), and prefers mb_* functions, but will fallback to iconv if a charset isn't supported by the mb_* functions.

A list of aliased charsets is maintained for both mb_* and iconv, where a supported charset exists for an alias. This is useful for mail and http parsing as other systems may report encodings not recognized by mb_* or iconv.

Charset lookup is done by removing non-alphanumeric characters as well, so UTF8 will always be matched to UTF-8, etc.

Usage

The following wrapper methods are exposed:

• mb_convert_encoding, iconv with MbWrapper::convert
• mb_substr, iconv_substr with MbWrapper::getSubstr
• mb_strlen, iconv_strlen with MbWrapper::getLength
• mb_check_encoding, iconv (for verification) with MbWrapper::checkEncoding

$mbWrapper = new \ZBateson\MbWrapper\MbWrapper();
$fromCharset = 'ISO-8859-1';
$toCharset = 'UTF-8';

$mbWrapper->convert('data', $fromCharset, $toCharset);
$mbWrapper->getLength('data', 'UTF-8');
$mbWrapper->substr('data', 'UTF-8', 1, 2);

if ($mbWrapper->checkEncoding('data', 'UTF-8')) {
    echo 'Compatible';
}
