Composer usage tutorial-Concise tutorial

Composer is a dependency management tool for PHP.

To use and install Composer, make sure that PHP (version 5.3.2 +) is installed correctly and that the environment variable for PHP is set (that is, the php version number can be displayed using the command php-v).

Installation of Composer

Windows system

Installation directory.

For example, if you install it under D:\ Program Files\ Composer, this directory will be used to set the environment variables for Composer.

Download the composer.phar file to the installation directory.

Download the latest version: https://getcomposer.org/compo...

Download list page for each version: https://getcomposer.org/download

Create an execution file named composer.bat under the installation directory and fill in the file with the following line:

@ php "% ~ dp0composer.phar"% *

Set the Composer environment variable

On the computer desktop, right-click "computer"-> menu "Properties"-> "Advanced system Settings"-> under "Environment variables"-> "system variables" to find the Path entry, edit the variable value and add the Composer installation directory path characters at the end, such as: d:\ Program Files\ Composer (this is written according to your installation directory), remember to use English semicolons between multiple paths; separate.

Test it (use the DOS command window)

Composer-V

Linux system / Mac OSX system

Operate under the terminal command line.

Go to the temporary download folder (feel free, such as your own home directory)

# cd ~

Download the composer.phar file

# wget https://getcomposer.org/composer.phar

Move and rename composer.phar files to binary directory

# mv composer.phar / usr/local/bin/composer is equivalent to setting the Composer environment variable

Set execution permission. You must have execution permission.

# chmod 755 / usr/local/bin/composer

Test it

# composer-V
