php - 使用任何方法使用php将大文件下载到服务器

Question

第一次尝试：

我用过这段代码：（感谢user580950的回答）

// define some variables
$local_file = 'archive.tar';
$server_file = '/path/to/archive.tar';
$ftp_server = "1.2.3.4";
$ftp_user_name = "username";
$ftp_user_pass = "password";
$port_number = 123

$conn_id = ftp_connect($ftp_server, $port_number);

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

// try to download $server_file and save to $local_file
if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {
    echo "Successfully written to $local_file\n";
}
else {
    echo "There was a problem\n";
}
// close the connection
ftp_close($conn_id);

存档是一个大文件，少于2GB.

但几秒钟后，我看到了There was a problem。

第二次尝试：

$url = 'http://site.com/archive.tar';

file_put_contents("archive.tar", fopen($url, 'r'));

---

第三次尝试：

$fh = fopen(basename($url), "wb");
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_FILE, $fh);
curl_exec($ch);
curl_close($ch);

---

第四次尝试：

$fp = fopen (dirname(__FILE__) . '/archive.tar', 'w+');//This is the file where we save the    information
$ch = curl_init($url);//Here is the file we are downloading, replace spaces with %20
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
curl_setopt($ch, CURLOPT_FILE, $fp); // write curl response to file
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch); // get curl response
curl_close($ch);
fclose($fp);

第五个：

function download($file_source, $file_target) {
    $rh = fopen($file_source, 'rb');
    $wh = fopen($file_target, 'w+b');
    if (!$rh || !$wh) {
        return false;
    }

    while (!feof($rh)) {
        if (fwrite($wh, fread($rh, 4096)) === FALSE) {
            return false;
        }
        echo ' ';
        flush();
    }

    fclose($rh);
    fclose($wh);

    return true;
}


set_time_limit(0);

var_dump(download($url, 'archive.tar')); // Returns bool(false)

我应该感谢 SO 中的许多人使用他们的代码，但仍然没有运气。

Answer 1

试试ftp_pasv($conn_id, true);。
