How can multiple variables be handled in PHP navigation links?

When dealing with multiple variables in PHP navigation links, you can pass them through the URL as query parameters. This allows you to pass multiple variables between pages and retrieve them using the $_GET superglobal array. To create navigation links with multiple variables, simply append the variables to the URL using the "?" symbol followed by the variable names and values separated by "&".

<a href="page.php?variable1=value1&variable2=value2">Link Text</a>
