PHP如何实现一个基础的FTP文件上传示例？

本文共计279个文字，预计阅读时间需要2分钟。

使用PHP上传单个文件到FTP服务器的示例代码如下：

php

// 要上传的本地文件$local_file='./example.txt';

// FTP服务器上的路径$ftp_path='/data/example.txt';

// 创建FTP连接$conn_id=ftp_connect($host);

// 登录FTP服务器$login_result=ftp_login($conn_id, $usr, $pwd);

// 检查连接和登录是否成功if ($conn_id && $login_result) { // 上传文件 if (ftp_put($conn_id, $ftp_path, $local_file, FTP_BINARY)) { echo 文件上传成功！; } else { echo 文件上传失败！; }} else { echo 无法连接到FTP服务器！;}

// 关闭FTP连接ftp_close($conn_id);?>

php上传单个文件到ftp服务器的演示范例

// FTP access parameters $host = 'ftp.example.org'; $usr = 'example_user'; $pwd = 'example_password'; // file to move: $local_file = './example.txt'; $ftp_path = '/data/example.txt'; // connect to FTP server (port 21) $conn_id = ftp_connect($host, 21) or die ("Cannot connect to host"); // send access parameters ftp_login($conn_id, $usr, $pwd) or die("Cannot login"); // turn on passive mode transfers (some servers need this) // ftp_pasv ($conn_id, true); // perform file upload $upload = ftp_put($conn_id, $ftp_path, $local_file, FTP_ASCII); // check upload status: print (!$upload) ? 'Cannot upload' : 'Upload complete'; print "\n"; /* ** Chmod the file (just as example) */ // If you are using PHP4 then you need to use this code: // (because the "ftp_chmod" command is just available in PHP5+) if (!function_exists('ftp_chmod')) { function ftp_chmod($ftp_stream, $mode, $filename){ return ftp_site($ftp_stream, sprintf('CHMOD %o %s', $mode, $filename)); } } // try to chmod the new file to 666 (writeable) if (ftp_chmod($conn_id, 0666, $ftp_path) !== false) { print $ftp_path . " chmoded successfully to 666\n"; } else { print "could not chmod $file\n"; } // close the FTP stream ftp_close($conn_id);
