PHP Apprentice is a work in progress so any constructive feedback is appreciated.
## Contributing
The codebase is a static site generator. It takes the Markdown files in the `chapters` folder
and builds them with PHP templates in `assets/templates`. All of the setup is controlled from the
`config.php` file. In `config.php`, the different chapters are ordered and template variables are placed.
To make a change to a chapter, just edit the Markdown file and merge with `master` and Travis will automatically
build the page again. Any page additions need to be included in the `config.php` file.
### Running Locally
To develop locally, clone the repository and run `composer install` and `npm install` in your terminal.
Then, you can run `php apprentice build` to build all the pages and `php apprentice server` to start a
development server on `localhost:8080`. The development server automatically rebuilds pages on load,
so you can use it to easily view changes. To build the JavaScript and CSS, run `npm run build` or `npm run watch`.
PHP Apprentice is built with [Hugo](https://gohugo.io). To build the site locally, clone the repository, install Hugo and run `hugo server` with a terminal in the project root. All of the site pages are written in Markdown and stored in the content directory. To create a new page, the hugo generator will use the default template to generate the markdown file in the content folder: `hugo new test.md`.
## Roadmap
Moving forward, there are three sections I would like to add to the site:

<h1>Credits</h1>
<p>
PHP Apprentice was inspired by
<a href="https://gobyexample.com/">Go By Example</a> and by <a href="https://elixirschool.com/">Elixir School</a>. Both sites offer excellent, quality documentation in Go and Elixir and I want PHP Apprentice to provide the same
experience for the PHP programming language.

</ul>

PHP Apprentice was built using several open source projects, besides PHP itself.

<p>
PHP Apprentice is an online, open source book about the PHP programming language. PHP is one of the most popular platforms for building websites and web services. It is a great language that is easy to learn and allows you to build powerful and complex web applications very quickly.
</p>
<p>
The goal of PHP Apprentice is to be an easy to understand resource for learning how to write good code in PHP. There are a lot of PHP tutorials on the internet that use outdated practices or insecure code. I want this book to show how to write PHP code with quality.
</p>
<p>
The contents of PHP Apprentice are for beginners and experienced PHP developers. The book currently has content for learning the basics of the language. In the future, more pages will be added for more advanced topics like building websites, database integration and security.
</p>
<p>
PHP Apprentice is currently a work in progress. If you would like to give feedback or request a certain discussion topic, check out the <a href="https://github.com/restoreddev/phpapprentice" target="_blank">GitHub repository</a>.

<h1>Installing PHP</h1>
<h2>Windows 10</h2>
<ol class="body-ol">
<li>Download PHP from the <a href="https://windows.php.net/download">PHP For Windows</a> site. I recommend downloading the non-thread safe PHP 7.1 or 7.2 (unless you want to use Apache and you know if you do). You will also need to choose 32 bit (x86) or 64 bit (x64) depending on your version of Windows.</li>
<li>Download the corresponding Visual C++ Redistributable from the same site. For PHP 7.1, it is VC14 and for PHP 7.2, it is VC15.</li>
<li>Install the VC redistrubutable using the downloaded executable.</li>
<li>The PHP download comes in a zip folder. Extract the zip folder into your user directory in a folder named <code>php</code>. The path should look like <code>C:\Users\username\php</code>.</li>
<li>Next, we need to add PHP to your environment variables path. Open "System" under "Control Panel". Go to the "Advanced" tab and select "Environment Variables". In the "User variables" section, select "Path" and click the "Edit" button. You will see a list of different folder paths. Add the PHP path to the list using the "Add" button. The PHP path is the same folder where you extracted PHP.</li>
<li>Now, you can open PowerShell or Command Prompt and type <code>php -v</code> to verify PHP was installed correctly. It will return the installed version of PHP on your system.</li>
</ol>
<h2>MacOS</h2>
<p>Good news! Each version of MacOS comes with PHP by default. However, if you are running an older version of MacOS or OS X, then you will need to manually install a new version of PHP. To check your current version, open Terminal and type <code>php -v</code>. You will need at least PHP 7.1 on your computer to use all the features in these tutorials.</p>
<ol class="body-ol">
<li>Install <a href="https://brew.sh/">Homebrew</a>.</li>
<li>Run <code>brew install php</code> in Terminal.</li>
<li>Check your version is correct by running <code>php -v</code> in Terminal.</li>
</ol>

The word `interface` is a confusing term because it is used for so many different concepts.

<h2>Windows 10</h2>
<ol class="body-ol">
<li>Download PHP from the <a href="https://windows.php.net/download">PHP For Windows</a> site. I recommend downloading the non-thread safe PHP 7.1 or 7.2 (unless you want to use Apache and you know if you do). You will also need to choose 32 bit (x86) or 64 bit (x64) depending on your version of Windows.</li>
<li>Download the corresponding Visual C++ Redistributable from the same site. For PHP 7.1, it is VC14 and for PHP 7.2, it is VC15.</li>
<li>Install the VC redistrubutable using the downloaded executable.</li>
<li>The PHP download comes in a zip folder. Extract the zip folder into your user directory in a folder named <code>php</code>. The path should look like <code>C:\Users\username\php</code>.</li>
<li>Next, we need to add PHP to your environment variables path. Open "System" under "Control Panel". Go to the "Advanced" tab and select "Environment Variables". In the "User variables" section, select "Path" and click the "Edit" button. You will see a list of different folder paths. Add the PHP path to the list using the "Add" button. The PHP path is the same folder where you extracted PHP.</li>
<li>Now, you can open PowerShell or Command Prompt and type <code>php -v</code> to verify PHP was installed correctly. It will return the installed version of PHP on your system.</li>
</ol>
<h2>MacOS</h2>
<p>Good news! Each version of MacOS comes with PHP by default. However, if you are running an older version of MacOS or OS X, then you will need to manually install a new version of PHP. To check your current version, open Terminal and type <code>php -v</code>. You will need at least PHP 7.1 on your computer to use all the features in these tutorials.</p>
<ol class="body-ol">
<li>Install <a href="https://brew.sh/">Homebrew</a>.</li>
<li>Run <code>brew install php</code> in Terminal.</li>
<li>Check your version is correct by running <code>php -v</code> in Terminal.</li>

HTTP stands for Hypertext Transfer Protocol. It is a standard for how requests and responses should be formatted for
a server and a web browser. When you open a link in your web browser, you are sending a HTTP request to a server and it
is responding with a HTTP response. The browser then takes the response, parses it and displays it to the user.

In PHP, you usually use a separate web server program that accepts HTTP requests and passes them to PHP to create a response. Common examples of separate web server programs are Apache and Nginx. However, PHP has a built in web server we can use during development.
To use the development web server, open a terminal and a new folder for holding your code. Create a file called `index.php` and put this PHP code in it:

PHP Apprentice is an online, open source book about the PHP programming language. PHP is one of the most popular platforms for building websites and web services. It is a great language that is easy to learn and allows you to build powerful and complex web applications very quickly.
</p>
<p>
The goal of PHP Apprentice is to be an easy to understand resource for learning how to write good code in PHP. There are a lot of PHP tutorials on the internet that use outdated practices or insecure code. I want this book to show how to write PHP code with quality.
</p>
<p>
The contents of PHP Apprentice are for beginners and experienced PHP developers. The book currently has content for learning the basics of the language. In the future, more pages will be added for more advanced topics like building websites, database integration and security.
</p>
<p>
PHP Apprentice is currently a work in progress. If you would like to give feedback or request a certain discussion topic, check out the <a href="https://github.com/restoreddev/phpapprentice" target="_blank">GitHub repository</a>.
