Image Validation

I'm new in PHP and I'm trying to make an image validation with TYPE and SIZE but I've failed. Can anyone please help me ?

Here is my code:

if($fileName)
    {
        $filePath="images/admin/".$fileName;
        if(file_exists($filePath))
        {
            $a=gmdate("Yzhis");
            move_uploaded_file($_FILES["image"]["tmp_name"], "images/admin/".$a.$_FILES["image"]["name"]);
            $fileName=$a.$_FILES["image"]["name"];

        }
        else
        {
            move_uploaded_file($_FILES["image"]["tmp_name"], "images/admin/".$_FILES["image"]["name"]);

        }
    }

This code is uploading the files fine, but it's not doing the validation.

Thanks.

You can use both of this function. 

filesize ()

http://php.net/manual/en/function.filesize.php

getimagesize ()

http://php.net/manual/en/function.getimagesize.php

Get a complete list of GD and Image functions. http://www.php.net/manual/en/ref.image.php

Image validation can get as complex as you want, but the simplest way is good old getimagesize() function. Test its output against false and you're done.

You can use "gd" or a similar library to validate and manipulate images in PHP.
