In the context of PHP development, how do copyright laws and international jurisdictions impact the protection of source code from unauthorized use or distribution?

Copyright laws and international jurisdictions play a crucial role in protecting source code from unauthorized use or distribution. To safeguard your PHP code, it is important to include copyright notices in your files, use open-source licenses like GPL or MIT, and consider registering your code with the appropriate authorities. Additionally, enforcing your rights may require legal action in the jurisdiction where the infringement occurred.
