URL router patterns tool

This library allows to create local URL responses, for example, to use in unit tests.

Install:

composer require 'psf1/router-matcher'

How to use:

<?php

use Psf1\RouterMatcher\RouterMatcher;

class myServer {
    
  /**
   * Router matcher.
   *
   * @var \Psf1\RouterMatcher\RouterMatcher
   */
  protected $routerMatcher;

  /**
   * Creates a myServer instance.
   */
  public function __construct() {
    // Create the matcher.
    $this->routerMatcher = new RouterMatcher();
    // Add new routes. If we need a subfolder where the second
    // can have dynamic values, it must be declared after the 
    // fixed one.
    // The same with other levels.
    $this->routerMatcher->addRoute('/example');
    // To declare a dynamic value you must enclose it with '{}'.
    $this->routerMatcher->addRoute('/entity/level2/{session_key}');
    $this->routerMatcher->addRoute('/entity/{session_key}');
    $this->routerMatcher->addRoute('/other-entity/list');
    $this->routerMatcher->addRoute('/other-entity/{id}/childs');
  }
