# A Basic Introduction to PHP and Variables
A basic example of using PHP variables.
This tutorial will review how to define and use PHP variables when creating HTML output. Here is a basic sample of using a variable and the `echo` command to create a personalized hello mesage.
```php
Hello '.$name.'!';
?>
```
Variables are used to temporary store data and then reference that data later on in your code. For example, a visitor could fill out a contact form, the contact form data is then stored in a series of variables, and then later on could be used to display a personalized message and/or send a personalized email.
There are some rules when naming your variables:
- Variable names start with the `$` sign
- Variable names must start with a letter or an underscore
- Variable names can contain alpha-numeric characters and underscores
- Variable names 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.
## Steps
1. Open up a new file and name it variables.php.
2. Add the following code to the new PHP file:
```php
Links and Variables
Links and Variables
Use PHP echo and variables to output the following link information:
```
3. After the variables are defined use a series of `echo` statements to display the content. For example outputting the `$linkname` might look like this:
```php
'.$linkName.'';
?>
```
> [!Note]
> Add each value from the array one at a time. Test your PHP after each new line of PHP.
