# Installation

# Environment require

• PHP > 7.0
• Composer

# Composer

Composer is the most popular PHP package manager, and there are plenty of open source software in the community for you to choose from.

# Details

Pinatra is the first PHP framework to do true hands-off, which itself is only available as an library, but provides sophisticated routing capabilities and a detailed MVC architecture.

Here is the "Step by Step" tutorial:

# Make a new project folder

mkdir blog

# composer initialization

cd blog
composer self-update
composer init

Then press Enter until Search for a package, type pinatra/framework and press Enter. When you get version of the constraint to require (or leave blank to use the latest version), type ~0.0, then continue press Enter all the way until the end of the interaction.

At this point, executing ls -a appears as shown below:

# View composer.json

Now the content of composer.json should be as follows:

{
    "name": "user/blog",
    "require": {
        "pinatra/framework": "~0.0"
    },
    "authors": [
        {
            "name": "JohnLui",
            "email": "user@gmail.com"
        }
    ]
}

# Download all composer packages

Excuting shell command:

composer update

At this point you should get the vendor folder and expand it as shown below:

# Create index.php

This project's document root folder should be at the same level as the vendor, which is a security requirement. Create a new public folder:

mkdir public
cd public

Create a new index.php file:

touch index.php

Then fill it up with the following code:

<?php

require __DIR__.'/../vendor/autoload.php';

get('hi', function() {
  echo "I am Pinatra framework!";
});

# Use the single-threaded built-in web server of PHP to get our website live!

Make sure that the current path of the command line is under the public folder, and then run the following command:

php -S 0.0.0.0:8000
