超薄路线传递到另一个文件返回值

Question

I have a folder structure like this :

|/app 
|-/db/users.php
|/Slim
|/vendor
|index.php

and inside index.php:

require 'vendor/autoload.php';

$app = new Slim\App();

$app->get('/{action}/{type}/{props}', function ($request, $response, $args) {
    $jenis_user = strtolower($args['type']);
    $aksi = strtolower($args['action']);
    $prop = strtolower($args['props']);

    $target_loc = "";

    if($aksi == 'get'){

        // the parameter is using the following format
        // action=XX&type=YY&props=ZZ;
        $target_loc = "./app/db/users.php?action=". $aksi . "&type=" . $jenis_user . "&props=" . $prop ;

        // #Tips :: data extracted are in Array Format ::
        $file = file_get_contents($target_loc);
        $response->write(json_encode($file));

    }

    return $response;
});

My purpose is to get an integer value returned if I use the following path into the browser:

http://api.myweb.com/get/seller/totalNumber

But it seems the way I wrote the routing of passing parameter is mistaken: I got a warning of

Warning: file_get_contents(./app/db/users.php?action=get&type=seller&props=totalnumber): failed to open stream

How could I fix it?

Answer 1

You are trying to get a file with the name users.php?action=get&type=seller&props=totalnumber which doesn't exist, in the file:// protocol, when you really what to do this you need to extra specify the http or https protocol like this:

$content = file_get_contents('http://example.com/users.php?x=y');

and it will succeed.

Notice: this is a bad structur, it would be better when you define a function or class for this, it could be like this:

functions.php

function getUsers($type, $props) {
    // do your stuff
    return $yourUsers;
}

index.php or route file

include 'functions.php'; // include the functions

$app = new Slim\App();
$app->get('/{action}/{type}/{props}', function ($request, $response, $args) {
    $jenis_user = strtolower($args['type']);
    $aksi = strtolower($args['action']);
    $prop = strtolower($args['props']);

    if($aksi == 'get'){

        $users = getUsers($jenis_user, $prop); // execute the function to collect the user
        $response->write(json_encode($users ));
    }

    return $response;
});

Then you wouldn't need the file_get_contents().
