彩纸屋（彩纸屋少儿编程系统）学习版 V1.4.7

 A PHP string manipulation library with multibyte support. Compatible with PHP 5.4+, PHP 7+, and HHVM. ``` php s('string')->toTitleCase()->ensureRight('y') == 'Stringy' ``` Refer to the [1.x branch](https://github.com/danielstjules/Stringy/tree/1.x) or [2.x branch](https://github.com/danielstjules/Stringy/tree/2.x) for older documentation.

[Tests](#tests) * [License](#license) ## Why? In part due to a lack of multibyte support (including UTF-8) across many of PHP's standard string functions. But also to offer an OO wrapper around the `mbstring` module's multibyte-compatible functions. Stringy handles some quirks, provides additional functionality, and hopefully makes strings a little easier to work with! ```php // Standard library strtoupper('fòôbàř'); // 'FòôBàř' strlen('fòôbàř'); // 10 // mbstring mb_strtoupper('fòôbàř'); // 'FÒÔBÀŘ' mb_strlen('fòôbàř'); // '6' // Stringy s('fòôbàř')->toUpperCase(); // 'FÒÔBÀŘ' s('fòôbàř')->length(); // '6' ``` ## Installation If you're using Composer to manage dependencies, you can include the following in your composer.json file: ```json "require": { "danielstjules/stringy": "~3.1.0" } ``` Then, after running `composer update` or `php composer.phar update`, you can load the class using Composer's autoloading: ```php require 'vendor/autoload.php'; ``` Otherwise, you can
