Is there any way to install Composer globally on Windows?

Sure. Just put composer.phar somewhere like C:\php\composer.phar, then make a batch file somewhere within the PATH called composer.bat which does the following:

@ECHO OFF
php "%~dp0composer.phar" %*

The "%*" repeats all of the arguments passed to the shell script.

Then you can run around doing composer update all ya want!

Install Composer On Windows, you can use the Composer Windows Installer.

---

Go to php.exe located folder.

C:\wamp\bin\php\php5.5.12\

open cmd there, and execute below command.

php -r "readfile('https://getcomposer.org/installer');" | php

composer.phar will be downloaded in same folder.

Create folder named composer in C:// drive (or anywhere you wish, for upcoming steps, remember the path).

move composer.phar file to C://composer folder.

Create composer.bat file in same folder with contents below

@ECHO OFF
php "%~dp0composer.phar" %*

create file named composer without any extensions.

running command type NUL > composer in CMD will help to get it done quickly,

Open that file and place below contents inside it.

#!/bin/sh
dir=$(d=$(dirname "$0"); cd "$d" && pwd)
# see if we are running in cygwin by checking for cygpath program
if command -v 'cygpath' >/dev/null 2>&1; then
    # cygwin paths start with /cygdrive/ which will break windows PHP,
    # so we need to translate the dir path to windows format. However
    # we could be using cygwin PHP which does not require this, so we
    # test if the path to PHP starts with /cygdrive/ rather than /usr/bin.
    if [[ $(which php) == /cygdrive/* ]]; then
        dir=$(cygpath -m $dir);
    fi
fi
dir=$(echo $dir | sed 's/ /\ /g')
php "${dir}/composer.phar" $*

Save.

Now set path, So we can access composer from cmd.

Show Desktop.

Right Click My Computer shortcut in the desktop.

Click Properties.

You should see a section of control Panel - Control Panel\System and Security\System.

Click Advanced System Settings on the Left menu.

Click Environment Variables towards the bottom of the window.

Select PATH in the user variables list.

Append your PHP Path (C:\composer) to your PATH variable, separated from the already existing string by a semi colon.

Click OK

Restart your machine.

Or, restart explorer only using below command in CMD.

taskkill /f /IM explorer.exe
start explorer.exe
exit

This may be useful to someone:

On Windows 7, if you've installed Composer using curl, it can be found in similar path:

C:\Users\<username>\AppData\Roaming\Composer

---

Well, now this question is a bit obsolete as there is now an official installer which "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."

You can get it at : http://getcomposer.org/doc/00-intro.md#installation-windows

---

A bit more generic if you put the batch in the same folder as composer.phar:

@ECHO OFF
SET SUBDIR=%~dp0
php %SUBDIR%/composer.phar %*

I'd write it as a comment, but code isn't avail there

---

Start > Computer : Properties > Change Settings > Advanced > Environment Variables > PATH : Edit [add this string (without "") at the end of line ";C:\<path to php folder>\php5.5.3"].. open cmd and type composer thats it :-)

---

I use Composer-Setup.exe and it works fine. Just in case you need to know where is the composer.phar (to use with PhpStorm) :

C:\ProgramData\ComposerSetup\bin\composer.phar

---

Unfortunately, all the good answers here didn't work for me. So after installing composer on windows 10, I just had to set system variable in environment variables and it worked.

sorry to dig this up, I just want to share my idea, the easy way for me is to rename composer.phar to composer.bat and put it into my PATH.

---

An alternative variant (see Lusitanian answer) is to register .phar files as executable on your system, exemplary phar.reg file:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.phar]
@="phar_auto_file"

[HKEY_CLASSES_ROOT\phar_auto_file\shell\open\command]
@="\"c:\\PROGRA~1\\php\\php.exe\" \"%1\" %*"

Just replace the path to php.exe to your PHP executable. You can then also extend the %PATHEXT% commandline variable with .PHAR which will allow you to type composer instead of composer.phar as long as composer.phar is inside the %Path%.

I was having the same issue and when I checked the environment in Windows 7 it was pointing to c:\users\myname\appdata\composer\version\bin which didn't exists. the file was actually located in C:\ProgramData\ComposerSetup\bin Fixed the location in environment setting and it worked

---

you can install it using this command line

 echo @php "%~dp0composer.phar" %* > composer.bat
