How to Install PHP Composer on Raspberry Pi?

Composer is a package manager for PHP. It basically allows importing codes to the project & other work. It helps them to keep it up-to-date. It helps you to manage those dependencies. We all can use PHP composer in our machine just by installing it. But, while you are using it in Raspberry Pi we have to install properly Raspberry Os. It is the most important prerequisite. Without it, you can not be able to install and use it further. If you do not install Raspberry Pi Os then you can not open the terminal which was provided along with it. If you can not open the terminal you can not write proper commands to install the Composer or any other applications.
