I'm currently working on a PHP project and I need some help with calculating the distance between two coordinates using the Haversine formula. I've been searching online and trying different solutions, but I haven't had much success.
To give you some context, I'm working on a travel website where users can search for destinations and find the nearest attractions or accommodations. I have the latitude and longitude coordinates of each destination, and now I want to calculate the distance between the user's location and these destinations.
I've read that the Haversine formula is widely used for this purpose, so I was wondering if anyone could share a PHP program or script that calculates the distance using this formula. I'm familiar with PHP, but I haven't worked with this particular calculation before, so any code examples or explanations would be greatly appreciated.
Thanks in advance for your help!
