PHP cURL Multiple Asynchronous Http Requests

Today, We want to share with you PHP cURL Multiple Asynchronous Http Requests.In this post we will show you wordpress plugin require another plugin, hear for PHP Curl Examples – PHP cURL Post, Get, Header we will give you demo and example for implement.In this post, we will learn about Building a REST client with asynchronous calls using PHP and curl with an example.

PHP cURL Multiple Asynchronous Http Requests

There are the Following The simple About PHP cURL Multiple Asynchronous Http Requests Full Information With Example and source code.

As I will cover this Post with live Working example to develop php curl without waiting for response, so the synchronous and asynchronous request in php is used for this example is following below.

PHP: Setting cURL timeout options.



PHP: Set custom headers with cURL


$url = 'http://localhost/test/file.php';
$ch = curl_init($url);

$customHeaders = array(
    'Accept-Encoding: gzip, deflate, br',
    'Cookie: PHPSESSID=BBRP012565Iidjkd8965;',
    'Referer: https://www.google.com/'
);

curl_setopt($ch, CURLOPT_HTTPHEADER, $customHeaders);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

$response = curl_exec($ch);
$data =  json_decode($response,true);

if(curl_errno($ch)){
    throw new Exception(curl_error($ch));
} else {
	print_r($data);
}



Using sleep to add delay or increase execution time


";
echo date('H:i:s');
?>

sleep(30);



php curl_exec stopped


$ch = curl_init(); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); 
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10); 
curl_setopt($ch, CURLOPT_TIMEOUT, 10); 
curl_setopt($ch, CURLOPT_URL, "https://myurl"); 
curl_setopt($ch, CURLOPT_POSTFIELDS, "post_field1=value1"); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_FAILONERROR, false); 
$server_output = curl_exec ($ch); // <------ IT DIES HERE INSIDE 
 curl_close ($ch); 
return $server_output; 



Multiple asynchronous http calls using curl


Single curl request


";
echo fetchContent('https://your-domain-name.com/api/admin/php/products/fetched-product/fetch1.php');
echo "


";


echo '




';


echo "


";
echo fetchContent('https://your-domain-name.com/api/admin/php/products/fetched-product/fetch2.php');
echo "


";


echo 'fetched for: ' . (microtime(true) - $t1) . "\n";


multiple http requests using curl


 $c) {
$content[$i] = curl_multi_getcontent($c);
curl_multi_remove_handle($mh, $c);
}

curl_multi_close($mh);

echo "
";
echo $content[0];
echo "


";


echo '




';


echo "


";
echo $content[1];
echo "


";


echo 'fetched for: ' . (microtime(true) - $t1) . "\n";


PHP Sleep Functions


while (true) {
    $getProducts = CurlPage($YOUR_URL);
    $getPage1httpCode = $getProducts['httpCode'];
    if ($getPage1httpCode === 200) {
        $DATA = $getProducts['Data'];
        break;
    }
    sleep(rand(5, 10));
    $tracks++;
    if ($tracks === 5) {
        die('Sorry, Fatal Error');
    }
}
