Symfony's polyfill-util is a valuable tool in the world of PHP development. It facilitates portability of PHP codes by providing binary-safe string functions. This is achieved using the mbstring extension when available, optimizing your PHP operations and ensuring consistency even across different environments.
Using symfony/polyfill-util is straightforward. The package is easily installed into your project via Composer, a tool for dependency management in PHP. You can include this package in your project with the following command in your terminal:
composer require symfony/polyfill-util
After installation, the functions provided by this utility can be used in your PHP code like any native function. Here’s an example, assuming mbstring extension is not enabled in your server:
use Symfony\Polyfill\Mbstring;
$string = 'Hello, World!';
$length = Mbstring::mb_strlen($string);
echo $length; // Outputs: 13
In the above code, we have used the mb_strlen() function provided by the Mbstring class of the symfony/polyfill-util package to get the length of the $string.
For more detail on symfony/polyfill-util, its main functionality and how to use it, you can refer to the main Symfony Polyfill README documentation available on GitHub.
