Membuat Simple Service Menggunakan PHP ( Simple PHP Service App )

Disini kita akan membuat Simple Service Menggunakan PHP murni tanpa menggunakan framework. Tujuannya untuk:

1. Memahami cara kerja web service
2. Mampu membuat simple service menggunakan PHP
3. Mampu mengakses web service

Dibawah ini adalah struktur folder dari Web Service App yang akan kita buat, folder tersebut kita taruh di xampp/htdocs

Kodingan yang perlu kita buat & ketik :

1. File index.php

.<?php

ini_set('display_errors', 1);
error_reporting(E_ALL);

require __DIR__."/core/Bootstrap.php";

2. File config/Routes.php

<?php

$routes = [
'/users' => 'Users.php',
'/' => 'Home.php',
];

?>

3. File controller/Home.php

<?php

$url = $_SERVER['REQUEST_URI'];

//if use folder path
$urlArr = explode("index.php", $url);
if (count($urlArr) >= 2) {
$url = $urlArr[1];
}

//if use php -s localhost:8000
if(strpos($url,"/")!== 0) {
$url = "/$url";
}

//untuk menghandle url /
if($url == '/' && $_SERVER ['REQUEST_METHOD'] == 'GET') {
echo json_encode(array('service_name'  => 'PHP Service App', 'status' => 'running'));
}

4. File controller/User.php

<?php

$url = $_SERVER ['REQUEST_URI'];

//if use folder path
$urlArr = explode("index.php", $url);
if (count($urlArr) >= 2) {
$url = $urlArr[1];
}

//if use php -s localhost:8000
if(strpos($url,"/") !== 0){
$url = "/$url";
}

//untuk menghandle url /users
if($url == '/users' && $_SERVER ['REQUEST_METHOD'] == 'GET') {
$users = array(
array('id' => 1, 'name' => 'Sumatrana', 'email' => 'sumatrana@gmail.com', 'address' => 'Padang', 'gender' => 'Laki-Llaki'),
array('id' => 2, 'name' => 'Jawarianto', 'email' => 'jawarianto@gmail.com', 'address' => 'Cimahi', 'gender' => 'Laki-Llaki'),
array('id' => 3, 'name' => 'Kalimantio', 'email' => 'kalimantio@gmail.com', 'address' => 'Samarinda', 'gender' => 'Laki-Llaki'),
array('id' => 4, 'name' => 'Sulawesiani', 'email' => 'sulawesiani@gmail.com', 'address' => 'Makasar', 'gender' => 'Perempuan'),
array('id' => 5, 'name' => 'Papuani', 'email' => 'Papuani@gmail.com', 'address' => 'Jayapura', 'gender' => 'Perempuan'),
);
echo json_encode($users);
}

//untuk menghandle url /user/{ID}
if(preg_match("/users\/([0-9])+/", $url, $matches) && $_SERVER ['REQUEST_METHOD'] == 'GET'){
$users = array(
'1' =>array('id' => 1, 'name' => 'Sumatrana', 'email' => 'sumatrana@gmail.com', 'address' => 'Padang', 'gender' => 'Laki-Llaki'),
'2' => array('id' => 2, 'name' => 'Jawarianto', 'email' => 'jawarianto@gmail.com', 'address' => 'Cimahi', 'gender' => 'Laki-Llaki'),
'3' => array('id' => 3, 'name' => 'Kalimantio', 'email' => 'kalimantio@gmail.com', 'address' => 'Samarinda', 'gender' => 'Laki-Llaki'),
'4' => array('id' => 4, 'name' => 'Sulawesiani', 'email' => 'sulawesiani@gmail.com', 'address' => 'Makasar', 'gender' => 'Perempuan'),
'5' => array('id' => 5, 'name' => 'Papuani', 'email' => 'Papuani@gmail.com', 'address' => 'Jayapura', 'gender' => 'Perempuan'),
);
$user = $users[$matches[1]];

echo json_encode($user);
}
?>

5. File core/Bootstrap.php

<?php

require __DIR__.'/Router.php';
require __DIR__.'/../config/Routes.php';


$router = new Router;
$router->setRoutes($routes);

$url = $_SERVER ['REQUEST_URI'];
require __DIR__."/../controller/".$router->getFilename($url);

?>

6. File core/Router.php

<?php

class Router {

private $routes = [];

function setRoutes(Array $routes){
$this->routes = $routes;
}

function getFilename(string $url){
foreach($this->routes as $route => $file) {
if(strpos($url, $route) !== false) {
return $file;
}
}
}
}


?>

Sesudah di buat file kodingnya dan di masukan/susun sesuai struktur folder seperti di atas, saatnya eksekusi.

Cara Menjalankan Aplikasi

Untuk menjalan aplikasi saya menggunakan cara :

1. Pada browser buka localhost/php-service-app/index.php , jika benar akan muncul seperti di bawah ini.

2. Selanjutnya saya menggunakan tools dalam mengakses API, tools nya adalah aplikasi "Postman"

3. Buka aplikasi Postman Pilih menu GET >  masukan http://localhost/php-service-app/index.php >

    Send.

4. Cek data users masukan http://localhost/php-service-app/index.php/users

5. http://localhost/php-service-app/index.php/users/1
