อยากสอบถามเรื่องการ upload รูปแล้วผมต้องการที่จะให้หมุน auto โดยดูจากค่า exif อะครับ

    	if(!is_array($_FILES["photo"]['name'])) //single file
    	{
		$RandomNum   = time();	
		$random_digit=rand(0000,9999);
     	$images = $_FILES["photo"]["tmp_name"];
		$ImageName      = str_replace(' ','-',strtolower($_FILES['photo']['name']));
        $ImageType      = $_FILES['photo']['type']; //"image/png", image/jpeg etc.
		$Imagesize      = $_FILES['photo']['size'];
        $ImageExt = substr($ImageName, strrpos($ImageName, '.'));
        $ImageExt   = str_replace('.','',$ImageExt);
		$ImageName		=		str_replace($ImageName,$job_no,$ImageName);
       	$ImageName      = preg_replace("/\.[^.\s]{3,4}$/", "", $ImageName);
        $NewImageName = "Photo_".$ImageName.'_'.$RandomNum.'.'.$ImageExt;
		//$ret[$fileName]= $output_dir.$NewImageName;
			//$new_images = "photo_".$_FILES["photo"]["name"];
 				//move_uploaded_file($_FILES["photo"]["tmp_name"],$output_dir. $new_images);
			//copy($_FILES["fileUpload"]["tmp_name"],$output_dir.$_FILES["fileUpload"]["name"]);
//-------------------------------------------------------------------------------			
		$new_images = "Thumbnails_".$ImageName.'_'.$RandomNum.'.'.$ImageExt;
	//	copy($_FILES["photo"]["tmp_name"],"MyResize/".$_FILES["fileUpload"]["name"]);
		$width=100; //*** Fix Width & Heigh (Autu caculate) ***//
		$size=GetimageSize($images);
		$height=round($width*$size[1]/$size[0]);
		$images_orig = ImageCreateFromJPEG($images);
		$photoX = ImagesX($images_orig);
		$photoY = ImagesY($images_orig);
		$images_fin = ImageCreateTrueColor($width, $height);
		ImageCopyResampled($images_fin, $images_orig, 0, 0, 0, 0, $width+1, $height+1, $photoX, $photoY);
		ImageJPEG($images_fin,$output_dir."/".$new_images);
		ImageDestroy($images_orig);
		ImageDestroy($images_fin);
//------------------------------------------------------------------------------- Thumbnails					
	if($Imagesize > '500000'){	
		$width=1024; //*** Fix Width & Heigh (Autu caculate) ***//
		$size=GetimageSize($images);
		$height=round($width*$size[1]/$size[0]);
		$images_orig = ImageCreateFromJPEG($images);
		$photoX = ImagesX($images_orig);
		$photoY = ImagesY($images_orig);
		$images_fin = ImageCreateTrueColor($width, $height);
		ImageCopyResampled($images_fin, $images_orig, 0, 0, 0, 0, $width+1, $height+1, $photoX, $photoY);
		ImageJPEG($images_fin,$output_dir."/".$NewImageName,75);
		ImageDestroy($images_orig);
		ImageDestroy($images_fin);
//------------------------------------------------------------------------------- size more 500kb			
	}else {
	    	 	move_uploaded_file($_FILES["photo"]["tmp_name"],$output_dir. $NewImageName);
//------------------------------------------------------------------------------- size  less 500kb						
	}
