I'm fairly new to PHP and I need some guidance on using operators to perform calculations or comparisons on geographic coordinates. I've been working on a project that involves working with geographic data, and now I need to perform various calculations and comparisons on the coordinates.
For example, let's say I have two sets of coordinates, latitude and longitude, representing two different locations. I want to calculate the distance between these two locations or determine if they are within a certain radius of each other.
I would also like to be able to compare two sets of coordinates to see which one is further north, south, east, or west.
I've searched for resources and examples online, but I'm having trouble finding a clear explanation or a comprehensive guide on how to achieve this using PHP. Can anyone point me in the right direction or provide some code samples to help me understand how to work with geographic coordinates in PHP?
Any help or guidance would be greatly appreciated. Thank you!
