What is composer?

Composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on, and it will manage (install/update) them for you. Composer is not a package manager in the same sense as Yum or Apt are. Yes, it deals with 'packages' or libraries, but it manages them on a per-project basis, installing them in a directory (e.g., vendor) inside your project. By default, it will never install anything globally. Thus, it is a dependency manager.

4. Create and edit php.ini file.

Did you open cpanel file manager? Yes!. Ok now you need to create php.ini file in public_html folder. You can create php.ini files in other folders but I suggest you create php.ini file in public_html folder. PHP.ini file is most important to install composer on cpanel so don't forget to create php.ini file into public_html folder. Click on the file button from navbar to create a new “php.ini” file into “public_html” folder.




If you have a created PHP file in a public_html folder, edit it. Write and save change below information into php.ini file.


max_execution_time = 300
max_input_time = 300
memory_limit = 512M
suhosin.executor.include.whitelist = phar
detect_unicode = Off


5. Open Terminal.

Did you create and edit the php.ini file? Now you need to open terminal from cpanel dashboard to install composer on shared hosting cpanel. Actually I will use cpanel terminal to install composer. So cpanel is important to install composer in shared hosting. 


Let's check current php version again using cpanel terminal before start to install composer on cpanel. Run php --version command on cpanel terminal interface to see current php version. I suggest you use the latest version of php in cpanel shared hosting.


php - v


7. Install Composer.

Now you are ready to install composer on shared hosting cpanel. After clicking on the terminal you will see the terminal interface. Now you need to go to your folder where you want to install Composer. For example, I want to install composer into "public_html" folder. So I need to go “public_html” folder from terminal interface. 


cd public_html


Wait a minute, want to install composer in subfolder? You can also install composer in subfolder of public_html. Just you need to go subfolder to install composer on cpanel. If you want to know where exactly you need to install composer on cpanel then don't forget to read where can i install composer in cpanel? question.


cd public_html/subfolder


Now let's run composer programming code to install composer on shared hosting cpanel. Please make sure that you have a created php.ini file in public_html folder. This command will install latest version of composer into your selected folder.


php -r "readfile('');" | php -c php.ini


Want to check if Composer is installed in cpanel? You need to run composer command to check composer installed or not on shared hosting cpanel.




Not sure if you have Composer installed on the shared hosting cpanel? You will get a composer file in where you installed composer. You can see a composer folder in file manager root folder. If composer.phar file not working to install composer package files then don't forget to read why isn't composer.phar working on cpanel? question.




Want to use Composer now installed? After successfully installed composer you can easily use composer like this.


php composer.phar


Want to install Composer package files using cpanel composer now installed? Use cpanel composer to install "composer.json" files.


php composer.phar install


You can also use the shared hosting cpanel composer to install any single composer package file. Use composer require command to install any composer package file.
