FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

Method addVertex vs addEdge

addVertex: This method is used to add a vertex to the graph. A vertex represents a point or node in the graph. In the context of the Dijkstra algorithm, a vertex can be thought of as a location or node in a network. The addVertex method takes two parameters: the name of the vertex and an array of neighboring vertices (edges) with their corresponding edge weights. It adds the vertex and its associated edges to the graph.

addEdge: This method is used to add an edge between two vertices in the graph. An edge represents a connection or link between two vertices. In the context of the Dijkstra algorithm, an edge represents a cable route or path between two locations in a network. The addEdge method takes three parameters: the source vertex, the destination vertex, and the weight or cost of the edge. It establishes the connection between the source and destination vertices with the specified weight.

To summarize, addVertex is used to add a vertex with its neighboring edges to the graph, while addEdge is used to establish a connection (edge) between two vertices with a specified weight. Together, these methods allow you to build the graph representation required for the Dijkstra algorithm to find the shortest path between vertices in the network.
