How can PHP be used to extract and manipulate URL parameters in a way that simulates passing parameters to an index.php file through mod_rewrite?

To extract and manipulate URL parameters in PHP to simulate passing parameters to an index.php file through mod_rewrite, you can use the $_GET superglobal array to access the parameters passed in the URL. You can then manipulate these parameters as needed within your PHP code. 

// Example URL: http://example.com/index.php?param1=value1&param2=value2

// Accessing URL parameters
$param1 = $_GET['param1']; // value1
$param2 = $_GET['param2']; // value2

// Manipulating parameters
$newParam = $param1 . ' ' . $param2; // Concatenating param1 and param2

echo $newParam; // Output: value1 value2
