title: Upload large files to FTP with PHP
body: <p>I'm trying to upload large files with php to an ftp server.  I can upload small files, but I'm having trouble uploading larger files.  I have looked it up and found that I need to set upload_max_filesize and post_max_size, set ftp to passive mode, and set time limit to never.  I had no luck with setting the time limit, and what I have now isn't returning any errors, but it is also not uploading the file.  If you look at the <code>if (!$upload) {</code> line at the bottom, it should echo something, but it isn't.  More importantly, it just isn't working.  Any insight as to what is going wrong or what I need to do to make this work?  Thank you!</p>
  
  <pre><code>ini_set('upload_max_filesize', '50M');   
  ini_set('post_max_size', '50M');  
  
  $conn_id = ftp_connect($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;
  }
  
   // turn passive mode on
  ftp_pasv($conn_id, true);
  
  if($_FILES['upload_file']['name']!=''){
      $source_file = $_FILES['upload_file']['tmp_name'];
      $destination_file = $_FILES['upload_file']['name']; 
  
      // upload the file
      $upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY);
  
      // check upload status
      if (!$upload) {
              echo "FTP upload has failed!&lt;br /&gt;";
          } else {
              echo "Uploaded $source_file to $ftp_server as $destination_file&lt;br /&gt;";
          }       
  }
  </code></pre>
  
  <h2>UPDATE</h2>
  
  <p>I've discovered that I cannot set the upload_max_filesize value from the php page; also, I can't seem to get .htaccess to work: if I have an .htaccess file it results in a HTTP Error 500.  Also, I don't have access to php.ini.</p>
  
  <p>How else can I change the upload_max_filesize value?</p>
  
  <h2>More Information</h2>
  
  <p>My web administrator has told me that I am on an IIS windows-based system, so .htaccess files won't work.  Is there a way that I can affect the file upload size with web.config?</p>
