PHP: 使用CURL访问FTP

if (isset($_POST[‘Submit‘])) {
    if (!empty($_FILES[‘upload‘][‘name‘])) {
        $ch = curl_init();
        $localfile = $_FILES[‘upload‘][‘tmp_name‘];

        curl_setopt($ch, CURLOPT_URL, ‘ftp://ftp_user:ftp_password@ftp.domain.com/‘ . $_FILES[‘upload‘][‘name‘]);
        curl_setopt($ch, CURLOPT_UPLOAD, 1);
        curl_setopt($ch, CURLOPT_INFILE, $fp);
        curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localfile));
        curl_exec($ch);
        $error_no = curl_errno($ch);
        curl_close($ch);
        if ($error_no == 0) {
            $error = ‘File uploaded succesfully.‘;
        } else {
            $error = ‘File upload error.‘;
        }

    }
}

$curl = curl_init();
