PHP: 使用CURL访问FTP

今天要做FTP上传。本想用PHP自带的FTP函数来实现，结果发现这个模块没有编译进来，重新编译PHP太麻烦，改用其他方式实现吧

 FTP上传

if (isset($_POST['Submit'])) {
    if (!empty($_FILES['upload']['name'])) {
        $ch = curl_init();
        $localfile = $_FILES['upload']['tmp_name'];
        $fp = fopen($localfile, 'r');
        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.';
        }
    } else {
        $error = 'Please select a file.';
    }
}

从FTP下载

$curl = curl_init();
$target_ftp_file = 'ftp://192.168.1.12:/filepath/target.txt'; //完整路径

curl_setopt($curl, CURLOPT_URL, $target_ftp_file);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_VERBOSE, 1);
curl_setopt($curl, CURLOPT_FTP_USE_EPSV, 0);
curl_setopt($curl, CURLOPT_TIMEOUT, 300); // times out after 300s
curl_setopt($curl, CURLOPT_USERPWD, "user_name:password"); //FTP用户名：密码// Sets up the output file
$target_path = './data';
if (is_dir($target_path)) {
    $outfile = fopen($target_path . '/' . dest . txt);
    curl_setopt($curl, CURLOPT_FILE, $outfile);
    $info = curl_exec($curl);
    fclose($outfile);
    $error_no = curl_errno($curl);
    curl_close($curl);
}
