$datetofolder = strtolower($datetofolder);

$checkdirectory = $target_dir."$folder/$datetofolder";

if (!file_exists($checkdirectory))
{
mkdir($checkdirectory, 0777, true);
}

$filnename  = "$folder/$datetofolder/$prefix".md5(time().rand()).".$extension";
$target_file = $target_dir . $filnename;
if (in_array($extension, $notallowed))
{
$uploadOk = 0;
$senddata['status']  = 0;
$senddata['message'] = $shownotallowed;
return $senddata;
}
// Check file size
if ($_FILES[$index]["size"] > 10485760)

// echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
$senddata['status']  = 1;
$tempdata = array();
$tempdata['name']  = $filnename;
$tempdata['realname']  = $realfilnename;
$senddata['data'] = $tempdata;
$senddata['message'] = "File Uploaded successfully.";

?>


How to use the function:

<?php
if(isset($_POST['uploadfile']))
{
$filetoupload1 = uploadimgfile("filetoupload1",$folder="folder1",$prefix="file1_");
$filetoupload2 = uploadimgfile("filetoupload2",$folder="folder2",$prefix="file2_");
echo "<pre>";
print_r($filetoupload1);
echo "</pre>";
echo "<pre>";
print_r($filetoupload2);
echo "</pre>";
}
?>

<form method="POST" enctype="multipart/form-data">
<input type="hidden" name="uploadfile" value="1" />
<input type="file" name="filetoupload1" />
<input type="file" name="filetoupload2" />
