How can you pass variables to a PHP page using a Get-Variable in a link?

To pass variables to a PHP page using a Get-Variable in a link, you can append the variable and its value to the URL as a query string. This can be done by adding a '?' followed by the variable name, an '=', and the variable value. In the PHP page, you can then access the passed variable using the $_GET superglobal array.

// Link with variable passed as a query string
<a href="page.php?variable=value">Link</a>

// PHP page (page.php) to access the passed variable
<?php
if(isset($_GET['variable'])) {
    $variable = $_GET['variable'];
    echo "Variable value: " . $variable;
}
?>
