When it comes to installing Composer, there are two ways. In the next section, we’ll see how to install Composer. Popular PHP frameworks like Symfony, Laravel, Drupal and many more have already adopted Composer-based workflows in their development lifecycle. In fact, Composer has become a global standard when it comes to managing third-party PHP libraries. We’ll get back to this in detail later in this article. More importantly, it also creates composer.json and composer.lock files that will be used to track the dependencies of your project. This installs the phpmailer library and its dependencies in the vendor directory of your project. For example, if you want to install the phpmailer library by using Composer, you just need to run the following command in the root of your project.

In a nutshell, we need a tool which can be used to install libraries and manage application dependencies. But it had its own limitations, which Composer was created to address. In fact, before Composer, there was a popular tool called PEAR which was used to manage PHP extensions and libraries. That's where a dependency manager like Composer comes in. For example, a database abstraction layer (DAL) is a must-have for any PHP application, but there was no standard library or package, so many people ended up developing their own.Ĭertainly, there were a lot of options available at that time, but it was difficult to add dependencies, to keep track of them, and to manage your application in the long run.
