Image upload script - how to resize - php

Question

I'm new to programming and require some help regarding the below issue.
I have the below script that I guess controls the upload of the image.
Is there any easy way to add a autoresizer of the image to 1024x768?
public function index()
{
$validator = Validator::make(Input::all(), [
'image' => 'required|image|max:' . (1024 * 3),
]);
if ($validator->fails()) {
$messages = $validator->messages();
echo json_encode([
'return' => 'error',
'message' => $messages->first('image')
]);
} else {
$originalName = Input::file('image')->getClientOriginalName();
$extension = Input::file('image')->getClientOriginalExtension();
$size = Input::file('image')->getSize();
$type = (Auth::check()) ? Auth::user()->default_image_privacy : 'public';
$adult = Input::has('adult') ? Input::get('adult') : 0;
$adult = ($adult != 1) ? 0 : 1;
$status = (Settings::get('auto_approve_images') == 1) ? 'active' : 'pending';
$image = new Image;
$image->user_id = (Auth::check()) ? Auth::user()->id : 0;
$image->file_name = $originalName;
$image->file_extn = $extension;
$image->file_size = $size;
$image->status = $status;
$image->type = $type;
$image->adult = $adult;
$image->ip = Net::getIP();
$image->save();
$imageFolder = floor($image->id / 1000) + 1;
$imageFolder = md5($imageFolder);
$imageFolder = substr($imageFolder, 1, 10);
$imageFolder = trim($imageFolder);
$image->folder = $imageFolder;
$image->save();
$destinationPath = public_path('uploads/' . $imageFolder);
$fileName = $image->id . '.' . $extension;
Input::file('image')->move($destinationPath, $fileName);
$destinationPathThumb = public_path('thumb/' . $imageFolder);
if (! File::isDirectory($destinationPathThumb)) {
File::makeDirectory($destinationPathThumb, 0755, true);
}
$fileNameThumb = $image->id . '.' . $extension;
$thumbWidth = (int) Settings::get('thumb_width');
$thumbWidth = ($thumbWidth < 80) ? 100 : $thumbWidth;
$thumbHeight = (int) Settings::get('thumb_height');
$thumbHeight = ($thumbHeight < 80) ? 100 : $thumbHeight;
Thumb::create($destinationPath . '/' . $fileName, $destinationPathThumb . '/' . $fileNameThumb, $thumbWidth, $thumbHeight);

Thumb::create($destinationPath . '/' . $fileName, $destinationPathThumb . '/' . $fileNameMed, $medWidth, $medHeight);
echo json_encode([
'return' => 'success',
'imageUid' => $image->id
]);
}
exit();
}

You can resize the image with some fileuploader in the client side, you also can use server side tools such as imagemagic with command like this:
`convert $original_path -resize '1024x768^' -gravity Center -crop '1024x768+0+0' $resized_path`;
