uploading files problem

hurricane

I'm having troubles with uploading files. When I try to ftp, I get this error:

Warning: php_hostconnect: connect failed in /catchusers3/2012092/bradley/uploadpics.php on line 3

When using regular uploading, I get this error (only when I try to upload say more than 3)

STDERR:

Failed to find the "nothing" line (\n\n)! Premature end of script headers.

STDOUT:

(nothing)

Here's my code:

<?php
/* set up basic connection
$conn_id = ftp_connect("localhost");

// login with username and password
$login_result = ftp_login($conn_id, "site", "pword");

// 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";
   }
*/

foreach ($_FILES["userFile"]["error"] as $key => $error) {
   $uploaddir = 'uploads/';
   $file_name = basename($_FILES['userFile']['name'][$key]);
   if($file_name != "")
   { 
      $file_name = str_replace("\\","",$file_name);
      $file_name = str_replace("'","",$file_name);
      $file_type = $_FILES['userFile']['type'][$key];
      $temp_name = $_FILES['userFile']['tmp_name'][$key];

  $validate = validata($file_name, $file_type);
  uploadFile($file_name, $temp_name, $uploaddir, $error, $validate);
  addToMySQL($file_name, $validate);
   }
}

function validata($fileName, $file_type)
{
   $FILE_EXT = array('.jpg','.jpeg','.bmp','.gif','.png');
$FILE_MIMES=array('image/jpeg','image/jpg','image/gif','image/png','image/bmp');
   $file_ext = strtolower(substr($fileName,strrpos($fileName,".")));
   if (!in_array($file_type, $FILE_MIMES) && !in_array($file_ext, $FILE_EXT) ){
      $fileMessage = "Sorry, $file_name($file_type) is not allowed to be uploaded.<br>";
      echo "$fileMessage";
      return (false);
   }else{
      return (true);
   }
}

function addToMySQL($fileName, $valid)
{
   $link = mysql_connect("localhost", "uname", "pwerd") or die("Couldn't connect to database");

mysql_select_db('dbname') or die('Could not select database');
   if($valid == "TRUE")
   {
      $queryPK = "SELECT MAX(pk)FROM pics";
      $recSetPK = mysql_query($queryPK, $link);
      $rowPK = mysql_fetch_array($recSetPK);
      if($rowPK[0] == ""){
         $pk = 0;
      }else{
         $pk = $rowPK[0] + 1;
      }

  $queryPicNum = "SELECT MAX(picNum)FROM pics";
  $recSetPicNum = mysql_query($queryPicNum, $link);
  $rowPicNum = mysql_fetch_array($recSetPicNum);
  if($rowPicNum[0] == ""){
     $picNum = 0;
  }else{
     $picNum = $rowPicNum[0] + 1;
  }

  $queryInsert = "INSERT INTO pics VALUES($pk, '$fileName', $picNum)";
  mysql_query($queryInsert, $link) or die("Could not insert into db!");
   }
}


function uploadFile($fileName, $tempName, $uploadDir, $error, $valid)
{
   if($valid == "TRUE")
   {
      if($error == UPLOAD_ERR_OK)
      {
         $file = $uploadDir.$fileName;
         move_uploaded_file($tempName, $file);
         $fileMessage .= "$file uploaded successfully<br>";
         echo "$fileMessage";
      }
   }
}
?>

Thanks for any help you can give me. This problem seems like it's on the server side, but I'm no expert..
