Installing the AWS SDK for PHP Version
3

You can install the AWS SDK for PHP Version 3:

• As a dependency via Composer

• As a prepackaged phar of the SDK

• As a ZIP file of the SDK

Before you install AWS SDK for PHP Version 3 ensure your environment is using PHP version 5.5 or
later. Learn more about environment requirements
and recommendations.

Note

Installing the SDK via the .phar and .zip methods requires the Multibyte String PHP
extension to be installed and enabled separately.

Install AWS SDK for PHP as a
dependency via Composer

Composer is the recommended way to install the
AWS SDK for PHP. Composer is a tool for PHP that manages and installs the dependencies of your
project.

For more information on how to install Composer, configure autoloading, and follow other
best practices for defining dependencies, see getcomposer.org.

Install Composer

If Composer is not already in your project, download and install Composer.

For Windows, download and run the Composer-Setup.exe.

For Linux, follow the Command-line installation on
the Download Composer
page.

Add AWS SDK for PHP as a dependency
via Composer

If Composer is already
installed globally on your system, run the following in the base directory of
your project to install AWS SDK for PHP as a dependency:

composer require aws/aws-sdk-php

Otherwise type this Composer command to install the latest version of the AWS SDK for PHP
as a dependency.

php -d memory_limit=-1 composer.phar require aws/aws-sdk-php

Add autoloader to your php
scripts

To utilize the AWS SDK for PHP in your scripts, include the autoloader in your scripts, as
follows.

<?php
   require '/path/to/vendor/autoload.php';
?>

Installing by using the packaged
phar

Each release of the AWS SDK for PHP includes a prepackaged phar (PHP archive) that contains
all the classes and dependencies you need to run the SDK. Additionally, the phar
automatically registers a class autoloader for the AWS SDK for PHP and all its
dependencies.

You can download the
packaged phar and include it in your scripts.

<?php
   require '/path/to/aws.phar';
?>

Note

Using PHP with the Suhosin patch is not recommended, but is common on Ubuntu and
Debian distributions. In this case, you might need to enable the use of phars in the
suhosin.ini. If you don’t do this, including a phar file in your code will cause a
silent failure. To modify suhosin.ini, add the following line.

suhosin.executor.include.whitelist = phar

Installing by using the ZIP file

The AWS SDK for PHP includes a ZIP file containing all the classes and dependencies you need
to run the SDK. Additionally, the ZIP file includes a class autoloader for the AWS SDK for PHP
and its dependencies.

To install the SDK, download the .zip file, and then extract it into your project at a location you
choose. Then include the autoloader in your scripts, as follows.

<?php
   require '/path/to/aws-autoloader.php';
?>
