Laravel on linux. Will there be mentors who will enlighten the nuances of the installation?

Question

Composer

Lord developers. Decided to be enlightened in Php direction. I looked at reviews of frameworks and settled on Laravelka. Intuitively.
I thought that everything would be fine with the installation. But I stuck something. A little. And there is no specifics on the network.
Can someone share a good recipe and for the benefit of the community it will also be.
Stopped at the Composer installation.

curl -sS https://getcomposer.org/installer | php
The program 'php' is currently not installed. You can install it by typing:

On StackOverflow they gave a tip on

sudo apt-get install php5-cli

и далее

curl -sS https://getcomposer.org/installer | php
All settings correct for using Composer
Downloading...

Composer successfully installed to: /home/alex_mint/composer.phar
Use it: php composer.phar

file has been created.
The next step, as I understand it, is the Laravel installer.

composer global require "laravel/installer=~1.1"

No command 'composer' found, did you mean:
 Command 'compose' from package 'mime-support' (main)
composer: command not found

But error
I would appreciate comments

Answer 1

You have gaps in the very basics.
Start by learning:
- What is Linux
- How to run programs on linux
- Where to learn English in X days.
- What is command line
- What is php
- What is composer
It doesn't even make sense to answer your question. You will come in 30 minutes with a new one: "XXXX does not work for me"

Answer 2

php composer.phar global require "laravel/installer=~1.1"
