php 简单ftp文件上传范例

php上传单个文件到ftp服务器的演示范例

1. // FTP access parameters
2. $host = 'ftp.example.org';
3. $usr = 'example_user';
4. $pwd = 'example_password';
6. // file to move:
7. $local_file = './example.txt';
8. $ftp_path = '/data/example.txt';
10. // connect to FTP server (port 21)
11. $conn_id = ftp_connect($host, 21) or die ("Cannot connect to host");
13. // send access parameters
14. ftp_login($conn_id, $usr, $pwd) or die("Cannot login");
16. // turn on passive mode transfers (some servers need this)
17. // ftp_pasv ($conn_id, true);
19. // perform file upload
20. $upload = ftp_put($conn_id, $ftp_path, $local_file, FTP_ASCII);
22. // check upload status:
23. print (!$upload) ? 'Cannot upload' : 'Upload complete';
24. print "\n";
26. /*
27. ** Chmod the file (just as example)
28. */
30. // If you are using PHP4 then you need to use this code:
31. // (because the "ftp_chmod" command is just available in PHP5+)
32. if (!function_exists('ftp_chmod')) {
33. function ftp_chmod($ftp_stream, $mode, $filename){
34. return ftp_site($ftp_stream, sprintf('CHMOD %o %s', $mode, $filename));
35. }
36. }
38. // try to chmod the new file to 666 (writeable)
39. if (ftp_chmod($conn_id, 0666, $ftp_path) !== false) {
40. print $ftp_path . " chmoded successfully to 666\n";
41. } else {
42. print "could not chmod $file\n";
43. }
45. // close the FTP stream
46. ftp_close($conn_id);
