As Mark Baker pointed out, you’ll need to use something like Dijkstra’s algorithm to traverse a weighted graph (which is what you’ll have when you include distances). Here’s a simple distance function I found here: <?php /*::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::*/ /*:: :*/ /*:: This routine calculates the distance between two points (given the :*/ /*:: latitude/longitude of those … Read more

To match numbers preceded by # use (?<=#)\d+ (positive lookbehind for #, then a non-empty sequence of digits). To match numbers not preceded by # use (?<!\d|#)\d+ (negative lookbehind). This time however the “forbidden” preceding char is either a # or a digit. Of course, use both patterns with g (global) option. If you want … Read more
