etichetta: PHP, PHP5.5, cURL, CURLOPT_POSTFIELDS, File Upload, CURLFille, File di caricamento PHP

PHP utilizza la libreria libcurl creata da Daniel Stenberg per connettersi a vari server, i protocolli che supporta sono http、https、ftp、gopher、telnet、dict、file、ldap. Libcurl supporta anche certificati HTTPS, POST, PUT, FTP, ecc. Supporta anche il caricamento basato su form, proxy, cookie, autenticazione nome utente + password.

PHP utilizza la libreria cURL per avviare queste richieste HTTP. cURL dipende da libcurl7.10.5 o versioni successive.

In PHP 5.4 o precedenti, l'incapsulamento dei file di caricamento cURL è procedurale:

$ch = curl_init();
$data = array('name' => 'File1', 'file' => '@/path/to/file.png');
curl_setopt($ch, CURLOPT_URL, 'https://localhost/upload.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_exec($ch);

In PHP 5.5 o versioni successive, l'incapsulamento del file di caricamento cURL viene aggiornato alla classe CURLFille:

$ch = curl_init();
$data = array('name' => 'File1', 'file' => new CURLFille('/path/to/file.png'));
curl_setopt($ch, CURLOPT_URL, 'https://localhost/upload.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_exec($ch);
