I have a php form which allows uploading files. However, the files go to the server and I need them to go with the rest of the form via email to the specified email address. Can someone please help?

Here is the code I am currently using, and just need to add a section to have it send the uploaded file with the email:

PHP Code:
<?php
//--------------------------Set these paramaters--------------------------

// Subject of email sent to you.
$subject 'Quote Form'

// Your email address. This is where the form information will be sent. 
$emailadd ''

// Where to redirect after form is processed. 
$url 'l'

// Where to direct file upload.
$file'';

// Makes all fields required. If set to '1' no field can not be empty. If set to '0' any or all fields can be empty.
$req '0'

// --------------------------Do not edit below this line--------------------------
$text "Results from form:\n\n"
$space ' ';
$line '
'
;
foreach (
$_POST as $key => $value)
{
if (
$req == '1')
{
if (
$value == '')
{echo 
"$key is empty";die;}
}
$j strlen($key);
if (
$j >= 20)
{echo 
"Name of form element $key cannot be longer than 20 characters";die;}
$j 20 $j;
for (
$i 1$i <= $j$i++)
{
$space .= ' ';}
$value str_replace('\n'"$line"$value);
$conc "{$key}:$space{$value}$line";
$text .= $conc;
$space ' ';
}
mail($emailadd$subject$text'From: '.$emailadd.'');
echo 
'<META HTTP-EQUIV=Refresh CONTENT="0; URL='.$url.'">';{
}
if (((
$_FILES["file"]["type"] == "application/ai")
|| (
$_FILES["file"]["type"] == "application/postscript")
|| (
$_FILES["file"]["type"] == "application/cdr")
|| (
$_FILES["file"]["type"] == "application/dxf")
|| (
$_FILES["file"]["type"] == "applicationj/eps")
|| (
$_FILES["file"]["type"] == "application/pdf"))
&& (
$_FILES["file"]["size"] < 900000))
  {
  if (
$_FILES["file"]["error"] > 0)
    {
    echo 
"Return Code: " $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    echo 
"Upload: " $_FILES["file"]["name"] . "<br />";
    echo 
"Type: " $_FILES["file"]["type"] . "<br />";
    echo 
"Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
    echo 
"Temp file: " $_FILES["file"]["tmp_name"] . "<br />";

    if (
file_exists("upload/" $_FILES["file"]["name"]))
      {
      echo 
$_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      
move_uploaded_file($_FILES["file"]["tmp_name"],
      
"upload/" $_FILES["file"]["name"]);
      echo 
"Stored in: " "upload/" $_FILES["file"]["name"];
      }
    }
  }
else
  {
  echo 
"Invalid file";
  }
?>

I have removed the email address and URL in the code for posting on this forum. I am fairly new to PHP and any help would be greatly appreciated! Thank you.
