Are there any specific PHP functions or methods that can simplify variable passing through links?

When passing variables through links in PHP, you can use the `http_build_query()` function to simplify the process. This function takes an array of variables and builds a URL-encoded query string, which can then be appended to the URL in the link. This helps in passing multiple variables without manually constructing the query string. 

// Example of using http_build_query() to simplify variable passing through links
$variables = array(
    'name' => 'John',
    'age' => 30,
    'city' => 'New York'
);

$queryString = http_build_query($variables);
$link = 'example.php?' . $queryString;

echo '<a href="' . $link . '">Click here</a>';
