How can PHP scripts be adapted to work with SSL encryption without major code changes?

To adapt PHP scripts to work with SSL encryption without major code changes, you can simply update the URLs in your scripts to use "https://" instead of "http://". This ensures that data transmitted between the server and client is encrypted and secure.

// Before
$url = "http://example.com/api";

// After
$url = "https://example.com/api";
