O PHP usa a biblioteca libcurl criada por Daniel Stenberg para conectar-se a vários servidores.Os protocolos suportados são http、https、ftp、gopher、telnet、dict、file、ldap. O Libcurl também suporta certificados HTTPS, POST, PUT, FTP, etc. Também suporta upload baseado em formulário, proxy, cookies, nome de usuário + autenticação de senha.

O PHP usa a biblioteca cURL para iniciar essas solicitações HTTP. O cURL depende da libcurl7.10.5 ou superior.

No PHP 5.4 ou anterior, o encapsulamento dos arquivos de upload cURL é procedural:

$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);

No PHP 5.5 ou posterior, o encapsulamento do arquivo de upload cURL é atualizado para a 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);
