Composer - a dependency management tool for PHP solidworks composer laravel avid media composer

1. Introduction to editing

Composer is a tool used in PHP to manage dependency relationships. You can declare the external libraries (libraries) you depend on in your project, and Composer will install these dependent library files for you.

2. Installation

To install Composer, you need to complete the following two steps:

First: Download Composer to your project directory. Use the following command:

$ curl -s (Composer web site)/installer | php
This command only checks a small amount of PHP configuration, and then downloads the composer.phar file to your working directory. This file is the Composer executable file. It Is a PHAR (PHP archive file, which can contain any file and can be executed from the PHP command line).
Second: Install Composer to the specified directory, that is, add the --install-diroption parameter after the command line. Use the following command:
$ curl -s (Composer web site)/installer | php -- --install-dir=bin

3. Use

Assume that you are creating a project and you need an output log in your project library, and you decide to use the monolog library. To add the monolog library to your project, simply create a composer.json file. The contents of this file describe the project's dependencies. An example is as follows: { "require": { "monolog/monolog": "1.2.*" }}
This simple line of text declares the dependent library -- monolog, version 1.2.
