Slim PHP Simple Setup

1) Download Package

slim.zip

2) Apache ModRewrite

the .htaccess contains the following code:

RewriteEngine On

# Some hosts may require you to use the `RewriteBase` directive.
# If you need to use the `RewriteBase` directive, it should be the
# absolute physical path to the directory that contains this htaccess file.
#
# RewriteBase /

Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php [QSA,L]

3) Get and Post Method test codes

the index contains the following code:

<?php

require 'Slim/Slim.php';
\Slim\Slim::registerAutoloader();

$app = new \Slim\Slim();

$app->get('/testget/:params+','testGet');
$app->post('/testpost','testPost');

$app->run();

function testGet($params){
   echo json_encode($params);
}

function testPost(){
   $app = \Slim\Slim::getInstance();
   $postvars = $app->request->post();
   echo json_encode($postvars);
}

?>

Silex PHP Simple Setup

1) Download Package

silex.zip

2) Apache ModRewrite

the .htaccess contains the following code:

RewriteEngine On

# Some hosts may require you to use the `RewriteBase` directive.
# If you need to use the `RewriteBase` directive, it should be the
# absolute physical path to the directory that contains this htaccess file.
#
# RewriteBase /

3) Test Functions

Objectives:
Get "/"
Get "/testget/1"
Post "/testpost" with form data key message (x-www-form-urlencoded)
Get "/testgetcontents" to call Get "/testget/"
Post "/testpostcontents" to call Get "/testpost/"  with form data key message (x-www-form-urlencoded)


Codes:
<?php

require_once __DIR__ . '/vendor/autoload.php';

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;

$app = new Silex\Application();

$app->get('/', function(){
return new Symfony\Component\HttpFoundation\Response("Hello Silex");
});


$app->get("/testget/{id}", function($id){
   return "testget - {$id}";
   
});

$app->post('/testpost', function (Request $request) {
    $message = $request->get('message');
    $reply = 'You have sent the following message:'.$message;
    return new Response($reply, 201);
});


$app->get('/testgetcontents',function(){
   $contents = file_get_contents('http://demo.razoph.com/silex/api/');
   return $contents;
});


function file_post_contents($url, $data, $username = null, $password = null){
   $postdata = http_build_query($data);

   $opts = array('http' =>
       array(
           'method'  => 'POST',
           'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
           'content' => $postdata
       )
   );

   if($username && $password)
   {
       $opts['http']['header'] .= ("Authorization: Basic " . base64_encode("$username:$password")); 
       // .= to append to the header array element
   }

   $context = stream_context_create($opts);
   return file_get_contents($url, false, $context);
}

$app->get('/testpostcontents',function(){
   $data = array("username" => "duser", "firstname" => "Demo", "message" => "testing", "email" => "example@example.com");  
   $contents = file_post_contents('http://demo.razoph.com/silex/api/testpost',$data);
   return $contents;
});


$app->run();
