Creating Variables
Building Variables
Variables are an essential part of any project. They hold data that can be modified or used later in a program.
We define variables in PHP with a $ sign and then we need to decide what the datatype for the variable will be. For a string of text make sure to put the text in quotes. If the value is a decimal or integer, no quotes are needed.
For Example, let's add these after the <?php in our code:
$name = "PHP Store";
$credit = 1000;
Combining text and Variables
Using a period (.), we can concatenate text and variables. Replace the echo line with the following:
echo "<h1>Welcome to ".$name."!</h1>";
echo "<h2>You have $".$credit." in your wallet.</h2>";";
Your code should look like this now:
<!DOCTYPE html>
<html>
<head>
<title>PHP Store</title>
</head>
<body>
<?php
$name = "PHP Store";
$credit = 1000;
echo "<h1>Welcome to ".$name."!</h1>";
echo "<h2>You have $".$credit." in your wallet.</h2>";
?>
</body>
</html>Refresh your browser and you should these sentences: Welcome to PHP Store! You have $1000 in your wallet.
If that worked, push your file to GitHub for the next step:
git add index.php
git commit -m"add variables"
git push origin master
