# Installation
## System Requirements
To install `League\Csv` you will need:
- the `mbstring` extension enabled in PHP
- at least **PHP >= 7.0.10** for version **9.0.0**
- at least **PHP >= 7.2.5** for version **9.6.0**
- at least **PHP >= 7.3** for version **9.7.0**
- at least **PHP >= 7.4** for version **9.8.0**
If you are using **PHP >= 8.0**, use version **9.6.2 or higher** for compatibility.
**Recommendation:** It is recommended to use the latest stable version of the `League\Csv` package in
combination with the latest PHP version.
<p class="message-notice">Since version <code>9.16.0</code> the <code>mbstring</code> extension is no
longer required but it is still recommended if you are using or plan to use any mb related stream filter</p>
## Composer Install
`League\Csv` is available on [Packagist](https://packagist.org/packages/league/csv) and can be installed using [Composer](https://getcomposer.org/):
```bash
composer require league/csv:^{{ site.data.project.version }}
```
## Manual Install
You can also use `League\Csv` without using Composer by downloading the library on Github.
1. Visit [the releases page](https://github.com/thephpleague/csv/releases) of the project.
2. Find the release of `League\Csv` for your version of PHP.
3. Click the **Source Code** link for preferred compression format.
The library is compatible with any [PSR-4](http://www.php-fig.org/psr/psr-4/) compatible autoloader.
Also, `League\Csv` comes bundled with its own autoloader script `autoload.php` located in the root directory.
```php
use League\Csv\Reader;
use League\Csv\Writer;
require '/path/to/league/csv/autoload.php';
// Your script starts here
// ...
```
where `path/to/league/csv` represents the path where the library was extracted.
