How to crop and upload photo using cropit jquery plugin with php

So I currently found this photo cropping plugin called cropit . Demos are here . So what I want to do is grab the cropped photo and upload the name of the photo to the mysql database and save it to a directory using php.

So far I have this :

HTML :

<form method="POST">
    <div class="image-editor">
        <div class="cropit-image-preview-container">
            <div class="cropit-image-preview"></div>
        </div>
            <div class="image-size-label">
            Resize image
        </div>
        <input type="range" class="cropit-image-zoom-input">
        <input type="hidden" name="image-data" class="hidden-image-data" />
        <button type="submit">Submit</button>
    </div>
</form>

jQUERY :

    $('form').submit(function() {
        // Move cropped image data to hidden input
        var imageData = $('.image-editor').cropit('export');
        $('.hidden-image-data').val(imageData);

        // Print HTTP request params
        var formValue = $(this).serialize();
        $('#result-data').text(formValue);

        // Prevent the form from actually submitting
        return false;
    });

All I need help is with the php set up code because when I crop the photo and select submit, jquery returns the serialize code, and all this code that I'm usually not familiar with appears. Here is a few characters of the serialized code jquery returns: 

image-data=data%3Aimage%2Fpng%3Bbase64%2CiVBORw0KGgoAAAANSUhE...

I got Hosch Nok's answer to work by not decoding the encoded data. Not calling:

$decoded = urldecode($encoded);

But working directly with the $encoded variable.

1. Saving the base64 encoded image

    <?php
    //save your data into a variable - last part is the base64 encoded image
    $encoded = "data%3Aimage%2Fpng%3Bbase64%2CiVBORw0KGgoAAAANSUhE";

    //decode the url, because we want to use decoded characters to use explode
    $decoded = urldecode($encoded);

    //explode at ',' - the last part should be the encoded image now
    $exp = explode(',', $decoded);

    //we just get the last element with array_pop
    $base64 = array_pop($exp);

    //decode the image and finally save it
    $data = base64_decode($base64);
    $file = 'data.png';

    //make sure you are the owner and have the rights to write content
    file_put_contents($file, $data);

2. Getting the filename of base64 encoded image

    $encoded = "data%3Aimage%2Fpng%3Bbase64%2CiVBORw0KGgoAAAANSUhE";
    $decoded = urldecode($encoded);
    $exp = explode(';', $decoded);
    $exp = explode(':', $exp[0]);
    $image = array_pop($exp);
    echo ($image);
