Prerequisites

• Shell access to a running Ubuntu system.
• Install PHP 5.3 or higher version.
• PHP’s package manager, `php-cli`, must be installed and available in your `PATH`

Installing PHP Composer on Ubuntu

The Composer’s official team provides a script to install PHP composer on Linux systems. You can download this script using the `curl` or `wget` command-line utility. Also, you can download it directly using the PHP script command line.

1. To download the `composer-setup` script, run the following command in a terminal:

   php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" 
   

2. Then execute the downloaded PHP script to install the composer on your Ubuntu system at the desired location. Use --install-dir to set the binary location and --filename to set the binary name. You can choose one of the below option:
   • Installing PHP composer system-wide: This will install composer in /uer/local/bin directory, that is accessible to all users:

     sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer
     sudo chmod +x /usr/local/bin/composer
     

   • Installing PHP composer for specific applicaiton: Sometimes you dont’ have permission to install it globally, like shared hosting account. Then you can configure this under you application as well. To install composer locally type:

     cd /path/to/php-application && mkdir -p bin 
     php composer-setup.php --install-dir=bin --filename=composer
     chmod +x bin/composer
     

     Make sure to replace /path/to/php-application with your application directory.

3. To see the installed composer version execute binary with -v command parameter.

   composer --version
   

   Output:
   Composer version 2.3.7 2022-06-06 16:43:28
   

Upgrade PHP Composer

The PHP composer has the ability to self-upgrade to the latest versions. If the composer is already installed on your system, just type the below command to upgrade the PHP composer to the latest version.

composer self-update

In my case, I already have latest version of composer. So receive the following message on terminal:

Output:
You are already using the latest available Composer version 2.3.7 (stable channel).

Working with PHP Composer

You have already installed and configured the composer on your system. The composer will help you to manage modules for your application. For example, to install a new module for your application.

Switch to the PHP application.

cd /path/to/php-application 

Run the following command to install psr/log module in the application.

composer require psr/log

Output:
Using version ^3.0 for psr/log
./composer.json has been created
Running composer update psr/log
Loading composer repositories with package information
Updating dependencies
Lock file operations: 1 install, 0 updates, 0 removals
  - Locking psr/log (3.0.0)
Writing lock file
Installing dependencies from lock file (including require-dev)
Package operations: 1 install, 0 updates, 0 removals
  - Downloading psr/log (3.0.0)
  - Installing psr/log (3.0.0): Extracting archive
Generating autoload files

Composer will automatically create or update composer.json file at application root directory. Now, the application can use the functionality provided by the module.

The above command will install the latest version of the module. You can also define the module version you want to install for your application. If the module is already installed, it will automatically downgrade/upgrade the package to the specified version.

composer require psr/log=1.0

The module no longer required can be removed with the following command.

composer remove psr/log

All the above commands also update composer.json file accordingly.

Conclusion

In this article, we have covered the steps for installing Composer on Ubuntu 22.04. By using Composer, you can easily manage the dependencies of your PHP projects and ensure that all necessary libraries are installed and up to date. Whether you are new to PHP development or an experienced developer, Composer can help you streamline your workflow and improve the quality of your projects.

Composer is a similar tool to npm for Node.js, pip for Python, and bundler for ROR. Composer 2 is the latest available version for your system with enhanced performance. We will use that version to install on our system.

This tutorial helps you to install and use PHP composer on Debian 11 Bullseye Linux system.

Prerequisites

• Shell access to a running Debian system with sudo privilege.
• Install PHP 5.3 or higher version on Debain.
• All newly installed systems recommended to follow initial server setup with Debian 11

Installing PHP Composer on Debian

A PHP script is provided by the official team to configure the composer on your system. You can download it with curl or wget command-line utility. Also, you can download it with the PHP script.

Open a terminal and run:

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" 

A composer-setup.php file will be created in current directory. Now execute this PHP script to install the composer at the desired location. Use --install-dir to set the binary location and --filename to set the binary name. You can install composer globally accessible for all users and projects or install locally for a specific project.

• To install composer globally, type:

  php composer-setup.php --install-dir=/usr/local/bin --filename=composer
  chmod +x /usr/local/bin/composer
  

• You can also install composer under the specific application. This is helpful for shared hosting environments, where you don’t have sudo or root access. To install composer locally for a specific project, type:

  cd /path/to/php-application && mkdir -p bin 
  php composer-setup.php --install-dir=bin --filename=composer
  chmod +x bin/composer
  

  Change /path/to/php-application with the actually application directory.

To see the installed composer version execute binary with -v command parameter.
