I'm working on a project where I need to create a countdown clock in PHP. The twist is that I want the end time to be variable, meaning the user can input their desired end time and the countdown should start from there. How can I achieve this?
I have some basic knowledge of PHP, but I'm not sure how to implement a countdown clock with a variable end time. It would be great if someone could help me out with the code or provide any insights on how to address this issue.
Any suggestions or examples would be really appreciated. Thank you in advance for your assistance!
