# A Basic Introduction to PHP and Arrays
A basic example of using PHP arrays.
This tutorial will review how to define and use PHP arrays when creating HTML output. Here is a basic sample of using an array and the `echo` command to create a personalized hello mesage.
```php
Hello '.$person['first'].' '.$person['last'].'!';
?>
```
Arrays are a special type of variable that can be used to store more than one piece of data. Each piece of data is assigned a key. The example above includes one array named `$person` and two keys `first` and `last`. Arays are often used to store a list of data:
```php
```
Or a group of information like an individuals profile:
```php
```
There are some rules when naming your arrays and keys:
- Array names must follow the same rules as variable names.
- Unlike variables names, array keys can start with numbers or be numeric.
- Array keys can use any alpha-numeric characters and underscores.
- Array keys are case sensitive.
## The End Goal
The goal of this series of lessons is to become comfortable with retrieveing data from a database and displaying the data in a web page. When working with database data the process roughly follows these steps:
1. Fetch data from the database.
2. Create a loop to iterate through the retrieved data.
3. Use if statements to check which data is ready for output.
4. Put the data into a series of variables and/or arays.
5. Use `echo` to output the variables and format them with HTML.
In this lesson we're going to focus on the last step, outputting data using HTML, variables, and the `echo` statement. This time the data will be placed in an array.
## Steps
1. Open up a new file and name it arrays.php.
2. Add the following code to the new PHP file:
```php

Links and Arrays
Use PHP echo and arrays to output the following link information:
```
3. After the array is defined use a series of `echo` statements to display the content. For example outputting the `$link['name']` might look like this:
```php
'.$link['name'].'';
?>
```
> [!Note]
> Add each value from the array one at a time. Test your PHP after each new line of PHP.
