System Requirements
-------------------

[](#system-requirements)

- PHP >= 7.0 but the latest stable version of PHP is recommended;
- `mbstring` extension;
- `intl` extension;

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

[](#installation)

The library is available on Packagist and can be installed using Composer. This is done by running the following command on a composer installed box:

```
$ composer require pdffiller/pdffiller-php-api-client

```

Most modern frameworks include Composer out of the box. However, please ensure that the following file is included:

```
// Include the Composer autoloader
require 'vendor/autoload.php';
```

### Troubleshooting

[](#troubleshooting)

If you have the following error:

```
[RuntimeException]
 Could not load package pdffiller/pdffiller-php-api-client in http://packagi
 st.org: [UnexpectedValueException] Could not parse version constraint ^5.2:
  Invalid version string "^5.2"

 [UnexpectedValueException]
 Could not parse version constraint ^5.2: Invalid version string "^5.2"

```

Try running

```
composer self-update

```

Also you might encounter the following:

```
Warning: require_once(../../vendor/autoload.php): failed to open stream: No such file or directory

```

This issue is easily fixed by installing composer dependencies:

```
composer install

```
