How Can I Execute cURL Requests Asynchronously in PHP?

Async Curl Request in PHP

Executing curl post requests asynchronously in PHP can enhance performance and prevent potential delays. Here's how you can achieve this using different methods:

Using Async cURL Functions

When using curl_multi_*, you can execute multiple cURL requests simultaneously. Here's an example code:

<code class="php">$curl = curl_init($request);
curl_setopt($curl, CURLOPT_URL, $url_onfleet);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_USERPWD, $api_onfleet);
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($curl, CURLOPT_ENCODING, "");  
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, '{&quot;destination&quot;:{&quot;address&quot;:{&quot;unparsed&quot;:&quot;'.$pickup_address.'&quot;},&quot;notes&quot;:&quot;'.$comments.'&quot;},&quot;recipients&quot;:[{&quot;name&quot;:&quot;'.$name.'&quot;,&quot;phone&quot;:&quot;+61'.$phone.'&quot;,&quot;notes&quot;:&quot;Number of riders: '.$riders.'&quot;}],&quot;completeBefore&quot;:'.$timestamp.',&quot;pickupTask&quot;:&quot;yes&quot;,&quot;autoAssign&quot;:{&quot;mode&quot;:&quot;distance&quot;}}');

$mh = curl_multi_init();
curl_multi_add_handle($mh,$curl);

$active = null;
//execute the handles
do {
    $mrc = curl_multi_exec($mh, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);

while ($active &amp;&amp; $mrc == CURLM_OK) {
    if (curl_multi_select($mh) != -1) {
        do {
            $mrc = curl_multi_exec($mh, $active);
        } while ($mrc == CURLM_CALL_MULTI_PERFORM);
    }
}
//close the handles
curl_multi_remove_handle($mh, $curl);
curl_multi_close($mh);</code>

Using pThreads

pThreads is a threading library for PHP. Here's how you can use it for async curl requests:

<code class="php">class Request1 extends Thread {
    public function run() {
        // Execute the first cURL request here
    }
}

class Request2 extends Thread {
    public function run() {
        // Execute the second cURL request here
    }
}

$req1 = new Request1();
$req1->start();
$req2 = new Request2();
$req2->start();</code>

Both methods allow asynchronous execution of curl requests, enabling better performance and efficient handling of parallel tasks.
