Send asynchronous request without waiting the response using guzzle : <p>I have the following two functions</p>

<pre><code>public function myEndpoint(){
    $this-&gt;logger-&gt;debug('Started');
    $this-&gt;guzzle-&gt;requestAsync('post', 'http://myurl.com/doNotWait')-&gt;wait();
    $this-&gt;logger-&gt;debug("I shouldn't wait");
}

public function doNotWait(){
    sleep(10);
    $this-&gt;logger-&gt;debug("You shouldn't wait");
}
</code></pre>

<p>Now what I need to see in my logs is:</p>

<pre><code>Started
I shouldn't wait
You shouldn't wait
</code></pre>

<p>But what I see </p>

<pre><code>Started
You shouldn't wait
I shouldn't wait
</code></pre>

<p>Also I tried using the following ways:</p>

<p><strong>Way #1</strong></p>

<pre><code>public function myEndpoint(){
    $this-&gt;logger-&gt;debug('Started');
    $this-&gt;guzzle-&gt;requestAsync('post', 'http://myurl.com/doNotWait', ['synchronous' =&gt; false])-&gt;wait();
    $this-&gt;logger-&gt;debug("I shouldn't wait");
}
</code></pre>

<p><strong>Way #2</strong></p>

<pre><code>public function myEndpoint(){
    $this-&gt;logger-&gt;debug('Started');
    $this-&gt;guzzle-&gt;requestAsync('post', 'http://myurl.com/doNotWait');

    $queue = \GuzzleHttp\Promise\queue()-&gt;run();
    $this-&gt;logger-&gt;debug("I shouldn't wait");
}
</code></pre>

<p>But the result is never the desired one. Any idea? I am using Guzzle 6.x.</p>
