How can the structure of URLs impact the way city names are stored and queried in a PHP database?

The structure of URLs can impact the way city names are stored and queried in a PHP database if the city names are directly included in the URL. To avoid issues such as special characters, spaces, or encoding problems, it is recommended to use URL parameters to pass city names to the PHP script. This way, the city names can be properly sanitized and processed before being used in database queries. 

// Example of using URL parameters to pass city names to PHP script
// URL: example.com/city.php?city=New%20York

$city = $_GET['city']; // Retrieve city name from URL parameter
$city = urldecode($city); // Decode URL-encoded city name
$city = mysqli_real_escape_string($connection, $city); // Sanitize city name for database query

// Use $city in database query to retrieve city information
