//Composer installation steps curl -sS https://getcomposer.org/installer | php All settings correct for using Composer Downloading... Composer successfully installed to: /Users/username/composer.phar |
The installer provided by composer check few PHP settings. If everything seems ok then it will download composer.phar in your working directory.PHAR stands for PHP archive, it’s an archive format for PHP which can be run on the command line, amongst other things.

The detect_unicode setting must be disabled. Add the following to the end of your `php.ini`: detect_unicode = Off The php.ini used by your command-line PHP is: /usr/local/etc/php/5.3/php.ini If you can not modify the ini file, you can also run `php -d option=value` to modify ini values on the fly. You can use -d multiple times. |
We have successfully installed composer in our mac machine. To access composer globally, let’s move it to /usr/local/bin directory.
|
1 2 |
//Move composer to /usr/local/bin directory sudo mv composer.phar /usr/local/bin/ |
Now composer.phar is moved to /usr/local/bin directory. Let’s create an alias in .bash_profile file.
|
1 2 |
//Composer alias alias composer="php /usr/local/bin/composer.phar" |
If you are using Z shell then create this alias in .zshrc file. After that reload your bash_profile by using command source ~/.bash_profile.
Now everything is done to check whether composer is installed successfully or not type composer in your terminal. If it installed successfully then you get following output.
