This article describes how to install and configure composer, a PHP dependency manager. Composer enables you to manage dependencies for each project independently, and is used by frameworks such as Laravel.
To install composer, follow these steps:
echo 'alias composer="php -d allow_url_fopen=On /home/username/composer.phar"' >> ~/.bashrc source ~/.bashrc
You can use composer with alternate PHP versions as well:
echo 'alias php="/opt/php/php-5.5.0/bin/php"' >> ~/.bashrc echo 'alias composer="/opt/php/php-5.5.0/bin/php -d allow_url_fopen=On /home/username/composer.phar"' >> ~/.bashrc source ~/.bashrc
