使用php通过ftp下载文件

Question

I'm using ftp_put() to download a file from another server. Everything (connection etc.) working but it wont download.

    ftp_chdir($conn_id, $destination_file); 
    $upload = ftp_put($conn_id, $name, $source_file, FTP_BINARY);

above is my code and its giving error "Can't change directory to"... when i out ftp_put without 'ftp_chdir' it didn't work so i used ftp_chdir . but still not working. $destination_file equal to a path and $name equal to a file. Please give me an idea what ai doing wrong? ps even $upload is returning true. But i can't find the file anywhere.

Answer 1

Use ftp_get not ftp_put

<?php

// define some variables
$local_file = 'local.zip';
$server_file = 'server.zip';

// 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);

// try to download $server_file and save to $local_file
if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {
    echo "Successfully written to $local_file\n";
} else {
    echo "There was a problem\n";
}

// close the connection
ftp_close($conn_id);

?>

ftp_get from PHP manual

Answer 2

This is my code, $source_file="http://example.com/ex/ex2/".$file_name; and $destination_file is equal to a path.

     $conn_id = ftp_connect($ftp_server);

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

    // check connection
    if ((!$conn_id) || (!$login_result)) {
          echo "FTP connection has failed!";
          echo "Attempted to connect to $ftp_server for user $ftp_user_name";
          exit;
      } else {
          echo "Connected to $ftp_server, for user $ftp_user_name";
      }

    // upload the file
    //ftp_chdir($conn_id, $destination_file); 
    $upload = ftp_get($conn_id, $destination_file, $source_file, FTP_BINARY);

    // check upload status
    if (!$upload) {
          echo "FTP upload has failed!";
      } else {
          echo "Downloaded $source_file";
      }

    // close the FTP stream
    ftp_close($conn_id);*/
