PHP - file upload will not move file to directory - php

Question

the file upload script is below...the storing of the file name in the DB is working fine, but the file is not being moved to the proper directory. the "Avatars" file is located in the "/httpdocs/" directory. I have set the permissions to "777".
<?php
require('dbconfig.php');
//generate a random string
function generateRandomString($length = 40) {
$characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
$randomString = '';
for ($i = 0; $i < $length; $i++) {
$randomString .= $characters[rand(0, strlen($characters) - 1)];
}
return $randomString;
}
$customname = generateRandomString();
$newimagename = "$customname." . pathinfo($_FILES['file']['name'],PATHINFO_EXTENSION);
$allowedExts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file"]["name"]);
$extension = end($temp);
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")

&& ($_FILES["file"]["size"] < 2000000)
&& in_array($extension, $allowedExts))
{
if ($_FILES["file"]["error"] > 0)
{
//echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
header ('Location: /dashboard.php?filetype=invalid');
exit();

{

}
