How can multiple values be passed through a URL in PHP using the GET method, and what considerations should be made when implementing this?

To pass multiple values through a URL in PHP using the GET method, you can concatenate the values with an ampersand (&) symbol. For example, if you want to pass two values "name" and "age", the URL would look like: `example.com/page.php?name=John&age=25`. When implementing this, ensure that the values are properly sanitized to prevent any security vulnerabilities, such as SQL injection or cross-site scripting attacks. 

// Example of passing multiple values through a URL using the GET method
$name = "John";
$age = 25;

$url = "example.com/page.php?name=" . urlencode($name) . "&age=" . urlencode($age);

// Redirect to the constructed URL
header("Location: $url");
exit;
