Multiple queries in parallel with PHP in API

Good morning. I am creating a script that queries an API. As the data inside the API became larger the requests needed to be split then for a query sometimes I have to query the API 4 or 5 times. I got in touch with the API support I use and was informed to do parallel queries using Thread.

I do not have much knowledge in programming and I'm using a half-ready code that I found on the internet. But I do not know how to modify it. Follow below:

<?php
// Classe que aguarda um tempo aleatorio e depois imprime algo na tela
class AguardaRand extends Thread {

    // ID da thread (usado para identificar a ordem que as threads terminaram)
    protected $id;

    // Construtor que apenas atribui um ID para identificar a thread
    public function __construct($id) { 
        $this->id = $id;
    }

    // Metodo principal da thread, que sera acionado quando chamarmos "start"
    public function run() {
        // Sortear um numero entre 1 e 4
        $tempo_rand = mt_rand(1, 4);

        // Aguardar o tempo sorteado
        sleep($tempo_rand);

        // Imprimir quem e' a thread e quanto tempo ela aguardou
        printf(
            "Sou a thread %d e aguardei %d segundos\n",
            $this->id,
            $tempo_rand
        );
    }
}

/// Execucao do codigo

// Criar um vetor com 10 threads do mesmo tipo
$vetor = array();
for ($id = 0; $id < 10; $id++) {
    $vetor[] = new AguardaRand($id);
}

// Iniciar a execucao das threads
foreach ($vetor as $thread) {
    $thread->start();
}

// Encerrar o script
exit(0);

I need to include a query in CURL for API and on each query I need to write the result to a variable can be an Array $ response [] so that I then process the grouped information.

Could anyone help me? I do not need the code. Just explaining to me the logic of this operation already helps me because I can get the script that queries the API unitariamente today and insert it inside.
