Single source shortest path (dijkstra algorithm) PHP implementation for a medical project, in which the single source shortest path algorithm will be used in case scoring. The idea of ​​​​the dijkstra algorithm for the single-source shortest path is as follows: If there is a shortest path from i to j (Vi...Vk, Vj), Vk is a vertex in front of Vj. Then (Vi...Vk) must also be the shortest path from i to k. Dijkstra is an algorithm that successively generates the shortest path with increasing length of the shortest path. For example: for the source vertex V0, first select the vertex Vi with the shortest length among its directly adjacent vertices, then it is currently known that the shortest distance from V0 to the Vj vertex dist[j]=min{dist[j],dist[ i]+cost[i][j]}. Assume G=, the source point is V0, U={V0} represents the set of marked vertices, dist[i] records the shortest distance from V0 to i, and cost[i][j] represents the cost of edge i to j. 1. Select the vertex i with the smallest dist[i] value from V-U, and add i to U; 2. The update is related to 1. Single-flow shortest path (d
