Message:

I'm trying to automate a process composed from multiple jobs. Every job had a goal, so I'm running a global job who is responsible for creating child jobs and add them to a batch instance.

# Instantiate the batches array

$batches = [];

# Retrieve destinations that have a dataset

$destinations = Destinations::where('dataset','like','%xx%')

                        ->where('dataset','like','%xx%')

                        ->get();

# Checking if there is some results

if(!empty($destinations)){

    foreach($destinations as $destination){

        # Current DateTime

        $dateTime = Carbon::now()->format('Y_m_d_h_i_s');

        # Create an array of batches for every location

        $batches[] = new AutoImport("auto_job_{$destination->reference}_{$dateTime}",$destination);

    }

}



# Creating batch chainning

$batch = Bus::batch($batches)

->then(function (Batch $batch) {



})->catch(function (Batch $batch, Throwable $e) {

    

})->finally(function (Batch $batch) {



})->dispatch();



return $batch->id;

At some point I'm gettin this error "Serialization of 'PDO' is not allowed" and I think is coming from this line new AutoImport("auto_job_{$destination->reference}_{$dateTime}",$destination); The fact that I send a whole object into the batches array

I'm not sure of that, so any help will be welcome.

Job abstract class

<?php



namespace App\Jobs;



use Illuminate\Bus\Queueable;

use Illuminate\Bus\Batchable;

use Illuminate\Contracts\Queue\ShouldQueue;

use Illuminate\Contracts\Queue\ShouldBeUnique;

use Illuminate\Queue\InteractsWithQueue;

use Illuminate\Queue\SerializesModels;

use Imtigger\LaravelJobStatus\Trackable;



abstract class Job implements ShouldQueue, ShouldBeUnique

{

    /*

    |--------------------------------------------------------------------------

    | Queueable Jobs

    | This job base class provides a central location to place any logic that

My Answer:
data is the process of converting a data structure or object into a format that can be easily stored or transmitted. In PHP, serialization is typically done using the `serialize()` function, which converts the data into a string that can be stored in a file or database.

For example, if you have an array of data that you want to serialize, you can do so like this:

php
$data = array('name' => 'John', 'age' => 30, 'city' => 'New York');
$serializedData = serialize($data);

// Store the serialized data in a file
file_put_contents('data.txt', $serializedData);


To unserialize the data and convert it back into its original form, you can use the `unserialize()` function:

php
$serializedData = file_get_contents('data.txt');
$data = unserialize($serializedData);

print_r($data);


This will output:


Array
(
[name] => John
[age] => 30
[city] => New York
)


Serialization is commonly used in PHP for storing complex data structures, caching data, or transmitting data between different systems. It is a convenient way to convert data into a format that can be easily manipulated and transported.
