Laravel Certification

Required Knowledge: PHP Basic

This repo has all the practice of my training in Laravel. It also serve as a Documentation for the most commonly used commands.

Chapter 1 - Installing Composer and Laravel Installer

Composer is an application-level package manager for the PHP programming language that provides a standard format for managing dependencies of PHP software and required libraries.

What we need for run these practice?

• php 7 installed on your machine
• console terminal

you need to have php installed, then you can check if you have it installed with the command:

php -v


alejandrodecastro@aledc:~$
PHP 7.1.23 (cli) (built: Nov 27 2018 16:59:25) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologies

Once we have verified that we have PHP, we proceed to install composer throught these four comands: Keep in mind that composer will be installed in the folder where you are.

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

php -r "if (hash_file('sha384', 'composer-setup.php') === '48e3236262b34d30969dca3c37281b3b4bbe3221bda826ac6a9a62d6444cdb0dcd0615698a5cbe587c3f0fe57a54d8f5') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

php composer-setup.php

php -r "unlink('composer-setup.php');"



For future updates always check the sourcecode:
https://getcomposer.org/download/

once installed we can verify if everything went well by executing the downloaded file composer.phar

php composer.phar

This will show among other things the list of available commands.

alejandrodecastro@aledc:~/test$ php composer.phar

So far we have installed composer locally, which means that it will only work in the local folder where it was downloaded.

It can be a good idea to install it Globally, this way it will be possible to run it in any folder you want.

For this you should run the following comand in the folder where you installed it previously:

mv composer.phar /usr/local/bin/composer

That's it, in this way we will have installed Composer on our computer.

For more info, check te official documentation Composer

Now, we can create our first project.

composer create-project --prefer-dist laravel/laravel hellolaravel

# Install specific version, in this case the 5.7 version.
composer create-project --prefer-dist laravel/laravel hellolaravel "5.7"

ahother way is throught the Laravel Installer:

composer global require "laravel/installer"

after this, you need to add the Path to your system.

in Mac:

nano ~/.bash_profile

then, add this line, save and restart the terminal.

export PATH=/usr/local/bin:$HOME/.composer/vendor/bin:$PATH

If everything went well, we will have Laravel installed and ready to run it in any folder.

You can finally try this by running

laravel new  name-of-my-project

then to launch the server we use this command:

php artisan serve

And now you can go to localhost:8000 and see your project running.

We complete the basic Laravel installation process :)
