$date=date('y-m-d');

foreach ($_FILES["attachments4"]["tmp_name"] as $key => $error) 
{
    if ($error == UPLOAD_ERR_OK) 
{

		@$tmp_name0 = $_FILES["attachments4"]["tmp_name"][0];
        @$name0 = $_FILES["attachments4"]["name"][0];
		
		@$tmp_name1 = $_FILES["attachments4"]["tmp_name"][1];
        @$name1 = $_FILES["attachments4"]["name"][1];
		@$tmp_name2 = $_FILES["attachments4"]["tmp_name"][2];
        @$name2 = $_FILES["attachments4"]["name"][2];

This function should do the trick as long as you have the PHP GD libraries.
Pass two file paths and it will copy $srcim into $destim and resize it to the size of $size.
For more details see this as that is where I got most of the code.

<?php
function makeThumbnail($srcim, $destim) {
$size = 200;
$thumb = ImageCreate(200, 200); 

$draw_from = $srcim;
$dim = GetImageSize($draw_from);
if($dim[0]>$dim[1])
{
$to_w = $size;
$to_h = round($dim[1]*($size/$dim[0]));
$to_x = 0;
$to_y = round($size-$to_h)/2;
}
else
{
$to_h = $size;
$to_w = round($dim[0]*($size/$dim[1]));
$to_y = 0;
$to_x = round($size-$to_w)/2;
}
if($dim[2]==1) {$from = ImageCreateFromGIF($draw_from);}
elseif($dim[2]==2) {$from = ImageCreateFromJPEG($draw_from);}
elseif($dim[2]==3) {$from = ImageCreateFromPNG($draw_from);} 
ImageCopyResized($thumb, $from, $to_x, $to_y, 0,  
0, $to_w, $to_h, $dim[0], $dim[1]); 
switch($dim[2]){
case 1:
ImageGIF($thumb, $destim);
break;		
case 2:
ImageJPEG($thumb, $destim);
break;
case 3:
ImagePNG($thumb, $destim);
break;
}
ImageDestroy($from);
ImageDestroy($thumb); 
return;
}
?>
