How to convert array to json-CodePudding

I was trying to convert an array to json and this is my code

<?php

namespace App\Http\Middleware;

use Carbon\Carbon;
use Closure;
use Illuminate\Http\RedirectResponse;
use Illuminate\Http\Request;
use Illuminate\Http\Response;
use Illuminate\Support\Facades\Log;

class SystemActivityLogger
{
    /**
     * Handle an incoming request.
     *
     * @param \Illuminate\Http\Request $request
     * @param \Closure(\Illuminate\Http\Request): (\Illuminate\Http\Response|\Illuminate\Http\RedirectResponse)  $next
     * @return Response|RedirectResponse
     */
    public function handle(Request $request, Closure $next)
    {
        Log::channel('rabbitmq_elk')->info($this->prepareLogData($request));
        return $next($request);
    }

    /**
     * Prepare log data and log it
     * @param Request $request
     * @return string
     */
    private function prepareLogData(Request $request): string
    {
      return json_encode([
           'ip' => $request->ip(),
           'url' => $request->url(),
           'agent' => $request->userAgent(),
           'date' => Carbon::now()->toDateTimeString(),
           'params' => $request->query(),
       ]);ل
    }
}

But then when I tested the output of this code, I realized that it returns a string. this is my code

 dd(is_string(json_encode([
            'ip' => $request->ip(),
            'url' => $request->url(),
            'agent' => $request->userAgent(),
            'date' => Carbon::now()->toDateTimeString(),
            'params' => $request->query(),
        ])));

return the true output

how can convert this array to json???

CodePudding user response：

JSON is a string format. The data is only JSON when it is in a string format.

To convert array to object

$object = json_decode(json_encode($array));

To convert array to collection

$collection = collect($array);

To convert array to json

$json  = json_encode($array);

CodePudding user response：

dd(is_string(json_encode([
    'ip' => $request->ip(),
    'url' => $request->url(),
    'agent' => $request->userAgent(),
    'date' => Carbon::now()->toDateTimeString(),
    'params' => $request->query(),
])));

Here used is_string function and it's return always boolean. So please remove is_string function and check again with die and dump. Like bellow...

dd(json_encode([
    'ip' => $request->ip(),
    'url' => $request->url(),
    'agent' => $request->userAgent(),
    'date' => Carbon::now()->toDateTimeString(),
    'params' => $request->query(),
]));
