PHP - Comment vérifier si Curl vraiment publier/envoyer la demande?

Vous pouvez utiliser curl_getinfo() pour obtenir le code d'état de la réponse de la sorte:

//set up curl to point to your requested URL
$ch = curl_init($fullcurl);
//tell curl to return the result content instead of outputting it
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

//execute the request, I'm assuming you don't care about the result content
curl_exec($ch);

if (curl_errno($ch)) {
    //this would be your first hint that something went wrong
    die('Couldn\'t send request: ' . curl_error($ch));
} else {
    //check the HTTP status code of the request
    $resultStatus = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    if ($resultStatus == 200) {
        //everything went better than expected
    } else {
        //the request did not complete as expected. common errors are 4xx
        //(not found, bad request, etc.) and 5xx (usually concerning
        //errors/exceptions in the remote script execution)

        die('Request failed: HTTP status code: ' . $resultStatus);
    }
}

curl_close($ch);

Ou, si vous avez des demandes à une sorte d'API qui renvoie des informations sur le résultat de la requête, vous devez réellement obtenir ce résultat et l'analyse. C'est très spécifique à l'API, mais voici un exemple:

//set up curl to point to your requested URL
$ch = curl_init($fullcurl);
//tell curl to return the result content instead of outputting it
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

//execute the request, but this time we care about the result
$result = curl_exec($ch);

if (curl_errno($ch)) {
    //this would be your first hint that something went wrong
    die('Couldn\'t send request: ' . curl_error($ch));
} else {
    //check the HTTP status code of the request
    $resultStatus = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    if ($resultStatus != 200) {
        die('Request failed: HTTP status code: ' . $resultStatus);
    }
}

curl_close($ch);

//let's pretend this is the behaviour of the target server
if ($result == 'ok') {
    //everything went better than expected
} else {
    die('Request failed: Error: ' . $result);
}
