# Getting started with composer-php
# Installing Composer on Ubuntu
Before we download and install Composer, we need to make sure our server has all dependencies installed.
First, update the package manager cache by running:
sudo apt-get update
Now, let's install the dependencies. We'll need
curl in order to download Composer and
php5-cli for installing and running it.
git is used by Composer for downloading project dependencies. Everything can be installed with the following command:
sudo apt-get install curl php5-cli git
Now let's install it:
curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer
This will download and install Composer as a system-wide command named composer, under /usr/local/bin. The output should look like this:
Output #!/usr/bin/env php All settings correct for using Composer Downloading... Composer successfully installed to: /usr/local/bin/composer Use it: php /usr/local/bin/composer
To test your installation, run:
And you should get output similar to this:
Output ______ / ____/___ ____ ___ ____ ____ ________ _____ / / / __ \/ __ `__ \/ __ \/ __ \/ ___/ _ \/ ___/ / /___/ /_/ / / / / / / /_/ / /_/ (__ ) __/ / \____/\____/_/ /_/ /_/ .___/\____/____/\___/_/ /_/ Composer version 1.0-dev (9859859f1082d94e546aa75746867df127aa0d9e) 2015-08-17 14:57:00 Usage: command [options] [arguments] Options: --help (-h) Display this help message --quiet (-q) Do not output any message --verbose (-v|vv|vvv) Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug --version (-V) Display this application version --ansi Force ANSI output --no-ansi Disable ANSI output --no-interaction (-n) Do not ask any interactive question --profile Display timing and memory usage information --working-dir (-d) If specified, use the given directory as working directory. ....
# Installing on Windows
Here we will simply use the installer.
This is the easiest way to get Composer set up on your machine.
Download and run Composer-Setup.exe. It will install the latest composer version and set up your
PATH so that you can just call
composer from any directory in your command line.
Note: Close your current terminal. Test usage with a new terminal: This is important since the PATH only gets loaded when the terminal starts.
Note-2: Set up
PATH in windows 10
- Right click on start up(windows logo)->
system ->Advance system settings->Environment variables->System variables[below box] ->select
- Click New and add this value
- Now open your terminal [cmd] and test
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.
Composer requires PHP 5.3.2+ to run. A few sensitive php settings and compile flags are also required, but when using the installer you will be warned about any incompatibilities.
To install packages from sources instead of simple zip archives, you will need git, svn, fossil or hg depending on how the package is version-controlled.
This section provides an overview of what composer-php is, and why a developer might want to use it.
It should also mention any large subjects within composer-php, and link out to the related topics. Since the Documentation for composer-php is new, you may need to create initial versions of those related topics.
