Are there any best practices or guidelines to follow when passing multiple variables through a link in PHP?

When passing multiple variables through a link in PHP, it is recommended to use the `http_build_query()` function to encode the variables into a query string. This function will handle any special characters and ensure that the variables are passed correctly. 

<?php
// Variables to pass
$var1 = 'value1';
$var2 = 'value2';
$var3 = 'value3';

// Build query string
$queryString = http_build_query(array(
    'var1' => $var1,
    'var2' => $var2,
    'var3' => $var3
));

// Create link with variables
$link = 'example.php?' . $queryString;

// Output link
echo '<a href="' . $link . '">Link</a>';
?>
