What role does PathInfo play in determining the behavior of PHP scripts accessed through URLs?

PathInfo is a PHP server variable that contains information about the path of the current script. It is commonly used in URL rewriting to determine the behavior of PHP scripts accessed through URLs. By analyzing the PathInfo variable, developers can extract relevant information from the URL and use it to control the execution flow of the script. 

$pathInfo = $_SERVER['PATH_INFO'];

// Example usage of PathInfo to determine behavior
if ($pathInfo == '/products') {
    // Display list of products
} elseif ($pathInfo == '/product/123') {
    // Display details of product with ID 123
} else {
    // Handle other cases
}
