我很好奇如何使用PHP通过FTP上传文件。假设我有上传表单，用户上传了一个文件。如何使用PHP将文件（不从临时目录移动到）到某个FTP主机？

答案 1

给你：

$ftp = ftp_connect($host, $port, $timeout);
ftp_login($ftp, $user, $pass);
 
$ret = ftp_nb_put($ftp, $dest_file, $source_file, FTP_BINARY, FTP_AUTORESUME);

while (FTP_MOREDATA == $ret)
    {
        // display progress bar, or something
        $ret = ftp_nb_continue($ftp);
    }
 
// all done :-)

为简洁起见，省略了错误处理。

请注意：您必须已安装并启用。ext-ftp

下面是一个代码示例

 $ftp_server="";
 $ftp_user_name="";
 $ftp_user_pass="";
 $file = "";//tobe uploaded
 $remote_file = "";

 // set up basic connection
 $conn_id = ftp_connect($ftp_server);

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

 // upload a file
 if (ftp_put($conn_id, $remote_file, $file, FTP_ASCII)) {
    echo "successfully uploaded $file\n";
    exit;
 } else {
    echo "There was a problem while uploading $file\n";
    exit;
    }
 // close the connection
 ftp_close($conn_id);
