In what scenarios would it be more appropriate to use $_SERVER to extract parameter strings instead of relying on mod_rewrite in PHP?

When you want to extract parameter strings from the URL in PHP without relying on mod_rewrite, you can use $_SERVER['REQUEST_URI'] to access the full URL path including the query string. This can be useful in scenarios where mod_rewrite is not available or not configured on the server. By parsing the query string from $_SERVER['REQUEST_URI'], you can extract the parameters and process them accordingly in your PHP script. 

// Extract parameter strings from URL using $_SERVER['REQUEST_URI']
$url = $_SERVER['REQUEST_URI'];
$parts = parse_url($url);
parse_str($parts['query'], $params);

// Access individual parameters
$param1 = $params['param1'];
$param2 = $params['param2'];

// Process the parameters as needed
// Example: echo the parameters
echo "Param1: " . $param1 . "<br>";
echo "Param2: " . $param2;
