What are some resources or tutorials that can help beginners understand how to pass variables through links in PHP effectively?

When passing variables through links in PHP, you can use query strings in the URL to send data from one page to another. To do this effectively, you can use the $_GET superglobal in PHP to retrieve the variables from the URL and use them in your code. 

// Sending variable through link
<a href="page2.php?variable=value">Link to Page 2</a>

// Retrieving variable on page2.php
<?php
if(isset($_GET['variable'])){
    $variable = $_GET['variable'];
    echo "The value of the variable is: " . $variable;
}
?>
