Question: I'm trying to make a website with links rotating around a circle. (Something like this) <http://i.imgur.com/i9DzASw.jpg?1> with the different images and texts leading to different urls. The image is one unified image that also rotates as the user scrolls. Is there anyway I can do this? Also is there a way to make the page height infinite so that the user never gets to the bottom of the page as they scroll? Thanks!

Here's the jsfiddle and the code that allows for the rotation of the image.

```
var $cog = $('#cog'),
    $body = $(document.body),
    bodyHeight = $body.height();

$(window).scroll(function () {
    $cog.css({
        'transform': 'rotate(' + ($body.scrollTop() / bodyHeight * 30000) + 'deg)'
    });
});

```

Answer: 
Ok, finally I had found the problem !!!

Encoding of PDO is the problem...

Just adjusted driver options and all works good!

```
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\'')

```

Thanks guys anyway!
how about whitelisting? ie allow only valid characters 

regex\_replace `[^-_.@a-zA-Z]` with `''`
