How can PHP variables be passed through URLs and accessed in PHP scripts?

To pass PHP variables through URLs and access them in PHP scripts, you can append the variables to the URL as query parameters using the `?` symbol followed by `key=value` pairs separated by `&`. In the PHP script, you can access these variables using the `$_GET` superglobal array. Example: 

// URL: http://example.com/script.php?name=John&age=25

$name = $_GET['name'];
$age = $_GET['age'];

echo "Name: $name, Age: $age";
