PHP Variables

A variable is used to store values so that it can used in any time.

A variable inside a PHP block of codes should looks like:

<?php

$var = Value;

?>

A typical example of PHP variable placed in HTML document should look like:

<html>
<head>
<title>PHP Tutorial</title>
</head>
<body>

<h1>PHP Variables Example</h1>

<?php

$shop = "osCommerce Online Shop";

echo 'The value of $shop variable is: ' . $shop;

?>

</body>
</html>

The output of the above PHP variables example should look like:

PHP Variables Example

The value of $shop variable is: osCommerce Online Shop

Note:

  1. We used 'The value of $shop variable is: ', not "The value of $shop variable is: ". Because we want to print out the $shop wording.
  2. We used the "dot" to join 'The value of $shop variable is: ' and $shop. The 'dot' is called PHP Concatenation operator and will be disussed in next PHP tutorial.
