The goal of PHP Apprentice is to be an easy to understand resource for learning how to write good code in the PHP programming language. There are a lot of PHP tutorials on the internet that use outdated libraries, insecure programming practices or inefficient code. I want this site to show how to write PHP code with quality.

If you want to follow along by writing code, start by downloading a code editor. I recommend
[Visual Studio Code](https://code.visualstudio.com/) or [Sublime Text](https://www.sublimetext.com/).
Next, create a new file in your editor called `basics.php` and save it anywhere on your computer like a folder
in your documents called `phpapprentice`. Now, we can write some PHP.
In the tradition of our ancestors, let's start with a hello world program.
All PHP files must start with a `<?php` tag unless it is for a html template.
(We will learn about html templates later.)

To write a string, you surround letters with single or double quotes.
Second, PHP stores text in strings. To write a string, you surround letters with single or double quotes.
Double quoted strings can hold special characters like `\n` which tells PHP to start a new line.
```php

echo "I am a string on a new line\n";
```
Third, all lines of code in PHP must end in a semi-colon.

Using semi-colons means we can write multiple statements on one line.
```php
echo "Hello"; echo " World\n";
echo "PHP"; echo " Apprentice\n";
```
To execute the code you have written, make sure you have [PHP installed](/installing-php.html).
Then, open a terminal app, either Terminal on MacOS or Powershell on Windows. In the terminal,
open the folder where you created the `basics.php` file using `cd`. For example, on Windows run `cd C:\%userprofile%\Documents\phpapprentice` and on Mac run `cd ~/Documents/phpapprentice`. Finally, you can execute the file by running `php basics.php`.
In your terminal, you should see:
```bash
Hello World!
I am some text
I am a string on a new line.
No semi-colon is a no-no
PHP Apprentice
```
With any code that we explore in future chapters, I recommend writing a PHP file for it.
It is a great way to get some practice with the language.
