Are there any specific syntax rules or conventions to follow when passing variables between PHP files using links or forms?

When passing variables between PHP files using links or forms, it is important to use the GET method to send data through the URL. This involves appending the variable name and its value to the URL as query parameters. In the receiving PHP file, you can access the passed variable using the $_GET superglobal array. 

<!-- Sending file (example.php) -->
<a href="receiver.php?variable_name=value">Click here</a>

<!-- Receiving file (receiver.php) -->
<?php
if(isset($_GET['variable_name'])){
    $received_variable = $_GET['variable_name'];
    echo $received_variable;
}
?>
