COMPOSER
Composer is a tool for
dependency management in PHP.
You declare the
libraries your project depends on and it will install (update) them
for you.
sudo apt update
sudo apt install wget php-cli php-zip unzip curl
curl -sS getcomposer.org/installer |php
To use Composer a project simply need a
composer.json file in its root directory.
This file defines the
dependencies of the project.
copy
{
"require": {
"nesbot/carbon": "2.12.*"
}
}
REQUIRE
We can edit composer.json manually, or we can
use commands (require/update).
mkdir /var/www/html/composer-test
cd /var/www/html/composer-test
composer require nesbot/carbon
sudo chown -R myuser.myuser composer-test
sudo chown -R catalin.catalin /home/catalin/.composer/
copy
require __DIR__ . '/vendor/autoload.php';
use Carbon\Carbon;
printf("Now: %s", Carbon::now());
printf("Lastweek: %s", Carbon::now()->subWeek());
UPDATE
Composer will
update the package if newer version found.
Also,
version constraint match with the one specified in the
composer.json.
composer outdated
composer clearcache
composer update
SELF-UPDATE
sudo composer self-update
composer -v
