How to install composer in project folder?

Question

ubuntu

Good evening. I want to install composer in a project. In the project folder, I need to execute the composer require cocur/slugify command, and then composer update and that's it? Am I doing it right?

If composer is not installed at all, run the following in your project folder

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === '93b54496392c062774670ac18b134c3b3a95e5a5e5c8f1a9f115f203b75bf9a129d5daa8ba6a13e2cc8a1da0806388a8') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

If you want to install globally so that you do not write this every time, do the following
After that, you can use it. And to install the package, run (provided that it is installed globally, otherwise instead of composer -> php composer.phar)

composer require cocur/slugify
composer update
