Why use mb_strlen instead of strlen in PHP?

The standard strlen function counts bytes, while mb_strlen correctly counts characters. For multibyte encodings like UTF-8, a single character (like an emoji) can be 4 bytes, so mb_strlen is required for accuracy.

What PHP extensions are required for these features?

Most features in this skill require the 'mbstring' extension for string handling and the 'intl' (Internationalization) extension for locale-aware formatting and ICU functionality.

Can this skill handle complex pluralization?

Absolutely. It covers the ICU MessageFormatter, which allows for sophisticated pluralization and gender rules in translated strings beyond simple 'singular/plural' logic.

Does this skill help with database character sets?

Yes, it provides implementation patterns for configuring PDO and MySQL to use utf8mb4, ensuring that 4-byte Unicode characters are stored and retrieved without corruption.

API Development

Implements robust internationalization and multibyte string handling in PHP using UTF-8 best practices and the ICU library.

The php-intl skill provides Claude with specialized expertise for handling complex character encoding, localization, and formatting tasks within PHP environments. It guides the implementation of mbstring and intl extensions to ensure correct multibyte string manipulation, locale-aware date/number/currency formatting, and advanced Unicode processing like transliteration and normalization. This skill is indispensable for developers building global applications that require high data integrity across diverse languages, regions, and character sets.
