Given a specified location I am looking for all the points that have a radiuses coving that point.
For example, lets say I have a database pull of pizza places, and they all deliver various distances (3mi, 10mi, 20mi, even a few 100mi, direct line will be fine for this). I put an address in and it searches this database to find all the locations that have a deliver radius covering my address.
The goal is to be able to search and list a display, so plotting radiuses on a map and seeing what covers is not a particularly good option. Initially I was thinking of plotting the distances as simple squares but the difference at 100mi is 41mi, large enough that it's a concern and hopefully there is a better option.
This is all going to be processed on a PHP site with a MySQL database. I've seen lots of resources on doing the opposite (find all points within a single radius) but nothing for this particular case.
Unlike the duplicate item this has been marked as I need to be able to have it use a radius attached to the points searched against, not a radius from the point it's searching from.
