A purely static UTF-8 Helper based on [mb\_string](https://php.net/mb_string) and [ext-intl](https://php.net/intl)

> For sure this is not new, and there is better out there, but this is small and does the job without a lot of noise

Installation
------------

[](#installation)

`Utf8` can be installed using composer:

```
composer require "fab2s/utf8"

```

`Utf8` is also included in [OpinHelper](https://github.com/fab2s/OpinHelpers) which packages several bellow "Swiss Army Knife" level Helpers covering some of the most annoying aspects of php programing, such as UTF8 string manipulation, high precision Mathematics or properly locking a file

Should you need to work with php bellow 7.1, you can still use [OpinHelper](https://github.com/fab2s/OpinHelpers) `0.x`

Prerequisites
-------------

[](#prerequisites)

`Utf8` requires [mb\_string](https://php.net/mb_string), [ext-intl](https://php.net/intl) is auto detected and used when available for UTF-8 Normalization

In practice
-----------

[](#in-practice)

`Utf8` offers replacement for most native string functions with support for UTF-8:

- `Utf8::strrpos(string string $str, string $needle, int $offset = null):int|false`

    UTF-8 aware [strrpos()](https://php.net/strrpos) replacement
- `Utf8::strpos(string $str, string $needle, int $offset = 0):int|false`

    UTF-8 aware [strpos()](https://php.net/strpos) replacement
- `Utf8::strtolower(string $str):string`

    UTF-8 aware [strtolower()](https://php.net/strtolower) replacement
- `Utf8::strtoupper(string $str):string`

    UTF-8 aware [strtoupper()](https://php.net/strtoupper) replacement
- `Utf8::substr(string $str, int $offset, int $length = null):string`

    UTF-8 aware [substr()](https://php.net/substr) replacement
- `Utf8::strlen(string $str):int`

    UTF-8 aware [strlen()](https://php.net/strlen) replacement
- `Utf8::ucfirst(string $str):string`

    UTF-8 aware [ucfirst()](https://php.net/ucfirst) replacement
- `Utf8::ucwords(string $str):string`

    UTF-8 aware [ucwords()](https://php.net/ucwords) replacement
- `Utf8::ord(string $chr):int|false`

    UTF-8 aware [ord()](https://php.net/ord) replacement
- `Utf8::chr(int $num):string|false`

    UTF-8 aware [chr()](https://php.net/chr) replacement

And some simple utility methods:

- `Utf8::normalize(string $string, int $canonicalForm = self::NORMALIZE_NFC):string`

    UTF-8 [ext-intl](https://php.net/intl) [Normalizer](https://php.net/normalizer.normalize)

    > **WARNING**: This method will do nothing in case `ext-intl` is not installed on the host This means it is up to you to make sure about it using `Utf8::normalizerSupport`or by adding `ext-intl` as a requirement to your project's `composer.json` file
- `Utf8::hasUtf8(string $string):bool`

    Tells if the input string contains some UTF-8
- `Utf8::isUtf8(string $string):bool`

    Tells if the input string is valid UTF-8
- `Utf8::replaceMb4(string $string, string $replace = ''):string`

    Replaces all [Utf8Mb4](https://stackoverflow.com/a/30074553/7630496) characters (aka mostly [emoji](https://en.wikipedia.org/wiki/Emoji))
- `Utf8::normalizerSupport(bool $disable = false):bool`

    Tells if [Normalizer](https://php.net/normalizer.normalize) is available or disable Normalizer support

Requirements
------------

[](#requirements)

`Utf8` is tested against php 7.2, 7.3, 7.4, 8.0 and 8.1
