尽管包含MIME类型，但不加载PDF类型文件

I have a form that aims to upload pdf's, MSWord docs, MSExcel files, and MSPowerpoint.

I'm tying to do a PHP validation as follows

<?php
if (isset($_FILES['fileupload'])){

  $filetype = array('application/pdf', 'application/msword', 'application/mspowerpoint');
  if (in_array($_FILES['fileupload']['type'], $filetype)){
    if(move_uploaded_file($_FILES["fileupload"]["tmp_name"], "/var/www/uploads/" . $_FILES["fileupload"]["name"])){
        $filename = basename($_FILES['fileupload']['name']);
        echo $filename;
      }//close moveupload
    }//close in_array
  }//close isset
}

?>

Why am I not able to upload pdf-like files but can upload MSword-like files? I have seen similar questions like this but I want to know why for this particular case it is not working for me.

    This is my test code:

    <?php 
ob_start("ob_gzhandler");
header('Content-Type: text/html; charset=utf-8');
  $filetype = array('application/pdf', 'application/msword', 'application/mspowerpoint');
  $type = $_FILES['fileupload']['type'];
  if (in_array($type, $filetype)){
    if(move_uploaded_file($_FILES["fileupload"]["tmp_name"], $_FILES["fileupload"]["name"])){
        $filename = basename($_FILES['fileupload']['name']);
        $show .= '<h2>saved sucessfully</h2>';
      }//close moveupload
    }//close in_array
    else{
      $show .= '$type = ' . $type . "
" ;
      $show .= "
file type: " . var_export($filetype,true). "
";
      $show .= "
  ###";
    }


echo <<<EOT
<!DOCTYPE html>
<html lang="en"><head><title>Test Bed</title></head></body><pre>
$show
</pre>
in_array
application/pdf
application/pdf
<form action="#" method="post" enctype="multipart/form-data">
<input type="file" name="fileupload" />
<button>Submit</button>
</form></body></html>

EOT;
?>

    Results

    saved sucessfully

    For uploads without the multiple set:

      if ($_FILES["fileupload"]["error"] == UPLOAD_ERR_OK) {
    if (!in_array($_FILES['fileupload']['type'], $filetype)){
      $tmp_name = $_FILES["fileupload"]["tmp_name"];
      $filename = basename($_FILES["fileupload"]["name"]);
      move_uploaded_file($tmp_name, $filename);
    }
  }
}
