This command sequence is used to install the Composer dependency manager for PHP on a Unix-based system.

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');": This command downloads the Composer installer file from the official website (https://getcomposer.org/installer) and saves it as composer-setup.php in the current directory.
php composer-setup.php: Running this command executes the PHP script (composer-setup.php) that was downloaded in the previous step. This script checks the integrity of the installer and sets up Composer on the system.
php -r "unlink('composer-setup.php');": After the installer script has been executed, this command deletes the composer-setup.php file from the current directory. This step is to clean up the unnecessary installer file.
sudo mv composer.phar /usr/local/bin/composer: Finally, this command moves the composer.phar executable file to the /usr/local/bin directory, which is typically included in the system's executable (PATH) environment variable. This allows you to run Composer commands from anywhere in the terminal by simply typing composer.

Once these commands are successfully executed, Composer should be installed on the system and ready to manage PHP package dependencies.
