Uploading file through FTP using PHP
提问by Paul
I'm curious how to upload file through FTP using PHP. Let's say I have upload form and user have uploaded a file. How to transfer the file (without moving from temp directory) to some FTP host using PHP?
我很好奇如何使用 PHP 通过 FTP 上传文件。假设我有上传表单并且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）传输到某个 FTP 主机？

Here you go:
干得好：
$ftp = ftp_connect($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 someting
$ret = ftp_nb_continue($ftp);
}
// all done :-)
Error handling omitted for brevity.
为简洁起见省略了错误处理。

Here is a code sample
这是一个代码示例
$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);

How about FTP upload via Curl? (Note: you can also use curl for SFTP, FTPS)
通过 Curl FTP 上传怎么样？（注意：你也可以使用 curl 进行 SFTP、FTPS）
<?php
$ch = curl_init();
$localfile = '/path/to/file.zip';
$remotefile = 'filename.zip';
$fp = fopen($localfile, 'r');
curl_setopt($ch, CURLOPT_URL, 'ftp://ftp_login:[email protected]/'.$remotefile);
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.';
}
?>

Here's a function to do it for you.
这是一个可以为您完成的功能。
function uploadFTP($server, $username, $password, $local_file, $remote_file){
// connect to server
$connection = ftp_connect($server);
// login
if (@ftp_login($connection, $username, $password)){
// successfully connected
}else{
return false;
}
ftp_put($connection, $remote_file, $local_file, FTP_BINARY);
ftp_close($connection);
return true;
}

用法：
uploadFTP("127.0.0.1", "admin", "mydog123", "C:\report.txt", "meeting/tuesday/report.txt");

FTP password must be in single quote otherwise it will not accept special characters
FTP密码必须是单引号，否则不接受特殊字符
$ftp_server="";
$ftp_user_name="";
$ftp_user_pass=''; // this is the right way
$file = "";//tobe uploaded
$remote_file = "";
