Installation

composer require hrishikesh214/php-api

And then in your file

require 'vendor/autoload.php';

Configurations

Before getting into PHPAPI we have to make some configs

In your root directory, create .htaccess file and paste following code

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?URL=$1 [L]

Documentation

Creating a client

$client = new phpapi\Client();

You can also pass base address

$client = new phpapi\Client("api/");

All child endpoints will be access after api/

Running Client

print_r($client->run(isset($_GET['URL']) ? $_GET['URL'] : ""));

This $client->run() returns response string, so you can store it in variable for further process or directly print it as response

Creating an Endpoint

$client->mount('GET', 'token', function(){
    //some calculations
    return $token;
});

Only some request methods are allowed : 'PUT', 'POST', 'DELETE', 'PATCH', 'GET', 'PURGE'

mount returns boolean value about whether endpoint is mounted successfully or not

Passing URL Parameters

Client will automatically pass url parameters to the response function

example is given below

$client->mount('GET', 'wish/:name/:age', function($props){
    return "Hi $props['name'], you are $props['age] years old!";
});

URI Parameters are directly passed to the responder function in an associative array according to the key passed in parameter

All other posted parameters will automatically get stored in $_POST

NOTE If parameter is define while mounting but not passes then it is given a null value

POST Endpoint

$respond = function(){
    return $_POST; //It will have all posted data!
};
$client->mount("POST", 'checkpost', $respond);

Trace Whole API

You can trace whole API Client with detailed configs of all endpoints mounted with a function

$client->trace(true|false);

If Above value is true final api result will also included api configs

This Also includes Requested configs

Example output:-

{
  "track": {
    "routes": {
      "POST": {
        "api/wish": {
          "base": "api/wish",
          "type": "POST",
          "params": [ ]
        },
        "name": {
          "base": "name",
          "type": "POST",
          "params": [ ]
        }
      },
      "GET": {
        "api/msg": {
          "base": "api/msg",
          "type": "GET",
          "params": [ ]
        },
        "api/wish": {
          "base": "api/wish",
          "type": "GET",
          "params": {
            "name": 3
          }
        },
        "name": {
          "base": "name",
          "type": "GET",
          "params": {
            "name": 3
          }
        },
        "/": {
          "base": "/",
          "type": "GET",
          "params": [ ]
        }
      }
    },
    "base": "",
    "request_blocks": [
      "api",
      "msg"
    ],
    "request_uri": "api/msg",
    "request_type": "GET"
  },
  "result": "trial"
}

In above example result will contain result coming from API

Setting Request Errors

There is a default error handler but you change it!

404

$client->set404([
    'error_type' => 404,
    'error_msg' => "Not Found"
]);

405

$client->set405([
    'error_type' => 405,
    'error_msg' => "Method Not Allowed"
]);

External Routes

Importing Routes from external file

You can also define routes in external file all you need is to use Helper Class.

For example (folder structure):-

|   myRoutes
|       - api.php
|   vendor (composer files)
|   index.php

//index.php
$client = new phpapi\Client();
$helper = new phpapi\Helper($client);

$helper->use('myRoutes/api.php' [, basename: 'api']);

// myRoutes/api.php

// You can define functions and also pass to callback
$myFunc = function($props){
            return "Good morning {$props['name']}";
        };

$routes = [
    [
        "match" => 'msg',
        "type" => "get",
        "callback" => function(){
            return "trial";
        }
    ],
    [
        "match" => 'wish/:name',
        "type" => "get",
        "callback" => $myFunc
    ],
    [
        "match" => 'wish',
        "type" => "post",
        "callback" => function(){
            return "Good morning {$_POST['name']}";
        }
    ]
];

$config = [
    'base' => 'api'
];

In above code $config['base']' will be act as base to all routes present in this file.

$routes will contain all routes.

Please maintain format else code will not work!
