Install the PHP AMQP extension

The AMQP extension provides PHP functions for communicating with AMQP-compatible servers such as RabbitMQ.

The AMQP extension supports PHP 5.6+. To use the latest version of the AMPQ extension, you will need PHP 7.4+.

Install the AMQP extension

Installing the extension involves the following steps:

  1. Install build dependencies (packages that are required to build the extension).
  2. Build the extension’s library file.
  3. Enable the extension in the PHP configuration.

Install build dependencies

Set environment variables for the package manager.

Terminal window
export DEBIAN_FRONTEND=noninteractive

Install a compiler and other packages that are required for building PHP extensions.

Terminal window
sudo apt-get -y install gcc g++ make autoconf libc-dev pkg-config

Install additional packages that are required to build the AMQP extension.

Terminal window
sudo apt-get -y install libssl-dev librabbitmq-dev

Build the extension

The PECL install command compiles the extension’s .so library file.

Terminal window
yes '' | sudo pecl8.4-sp install amqp

Enable the extension

Configure PHP to load the extension.

Terminal window
sudo bash -c "echo extension=amqp.so > /etc/php8.4-sp/conf.d/amqp.ini"

Restart PHP-FPM.

Terminal window
sudo service php8.4-fpm-sp restart

Verify the extension is enabled in PHP.

Terminal window
php8.4-sp -i | grep amqp

If the extension is enabled, you will see output like the following.
