ftp_fput — 上传已打开的文件到 FTP 服务器
$ftp,$remote_filename,$stream,$mode = FTP_BINARY,$offset = 0ftp_fput() 函数用来上传一个在已经打开的文件中的数据到 FTP 服务器。
ftpFTP\Connection 实例。
remote_filename远程文件路径。
stream打开的本地文件句柄，读取到文件末尾。
mode
传输模式只能为（文本模式）FTP_ASCII 或（二进制模式）FTP_BINARY 其中的一个。
offset远程文件上传的开始位置。
| 版本 | 说明 |
|---|---|
| 8.1.0 |
现在 ftp 参数接受 FTP\Connection
实例，之前接受 resource。
|
| 7.3.0 |
mode 参数现在可选。以前强制要求。

示例 #1 ftp_fput() 示例
<?php
// open some file for reading
$file = 'somefile.txt';
$fp = fopen($file, 'r');
// set up basic connection
$ftp = ftp_connect($ftp_server);
// login with username and password
$login_result = ftp_login($ftp, $ftp_user_name, $ftp_user_pass);
// try to upload $file
if (ftp_fput($ftp, $file, $fp, FTP_ASCII)) {
echo "Successfully uploaded $file\n";
} else {
echo "There was a problem while uploading $file\n";
}
// close the connection and the file handler
ftp_close($ftp);
fclose($fp);
?>
For directly inserting content into a file on an FTP host, you could also create a string stream wich streams directly to the ftp_fput function. This should create less overhead than first writing to any temp directories locally before streaming, as suggested here.<?php$string = "Your content goes here";$stream = fopen('data://text/plain,' . $string,'r');ftp_fput($this->connection,$pathTo,$stream, FTP_BINARY);?>If when using fput you get the one of the following errors:Warning: ftp_fput() [function.ftp-fput]: Opening ASCII mode data connectionWarning: ftp_fput() [function.ftp-fput]: Opening BINARY mode data connectionand it creates the file in the correct location but is a 0kb file and all FTP commands thereafter fail. It is likely that the client is behind a firewall. To rectify this use:<?phpftp_pasv($resource, true);?>Before executing any put commands. Took me so long to figure this out I actually cheered when I did :DWhen you have your file contents as a string, create temporary stream and use that as a file handle.<?php$contents = "This is a test file\nTesting 1,2,3..";$tempHandle = fopen('php://temp', 'r+');fwrite($tempHandle, $contents);rewind($tempHandle); ftp_fput($this->ftp, $filename, $tempHandle, FTP_ASCII);?>Make sure you chdir to remote directory before using ftp_put or else ftp_put will just return error that it cannot create file. After you do the chdir you should NOT pass the whole path of file to ftp_put but just basename (filename). See example for more info.Example:<?php$locpath = 'local_path/resources/js/test.js';$rempath = 'resources/js/';$remFile = 'test.js';ftp_chdir($this->conn_id, $rempath);ftp_put($this->conn_id, $remFile, $locpath, FTP_BINARY);?>This might be obvious to most of you, but make sure your stream isn't write-only. It has to be able to read from your stream in order to upload its contents.Took me a while trying to figure out why my uploaded file was 0B, and that was why.Using jopi paranoid fi's example, tmpfile() works on PHP 4 and 5 instead of using the php://temp file.This is a function i wrote to copy a complete directory to a FTP-Server-folder.function ftp_uploaddirectory($conn_id, $local_dir, $remote_dir){ @ftp_mkdir($conn_id, $remote_dir); $handle = opendir($local_dir); while (($file = readdir($handle)) !== false) { if (($file != '.') && ($file != '..')) { if (is_dir($local_dir.$file)) { ftp_uploaddirectory($conn_id, $local_dir.$file.'/', $remote_dir.$file.'/'); } else $f[] = $file; } } closedir($handle); if (count($f)) { sort($f); @ftp_chdir($conn_id, $remote_dir); foreach ($f as $files) { $from = @fopen("$local_dir$files", 'r'); @ftp_fput($conn_id, $files, $from, FTP_BINARY); } }}Example:$conn_id = @ftp_connect($server);@ftp_login ($conn_id, $username, $passwort);ftp_uploaddirectory($conn_id, 'mydirectory/', 'theftpdirectory/');@ftp_quit($conn_id);I hope you'll find it useful.If you want to pass a string containing the filename as source and not a resource handle use ftp_put() instead. Trivial but not mentioned here.
