How to remove $ and comma from form input using current php code?

Question

Here's sample of my input format

<script type="text/javascript" src="http://jquerypriceformat.com/js/jquery-1.9.1.min.js"></script>
<script type="text/javascript" src="http://jquerypriceformat.com/js/jquery.price_format.2.0.js"></script>
<script type="text/javascript" src="http://jquerypriceformat.com/js/ini.js"></script>
<label for="example6">Currency:</label>
<input id="example6" name="example6" value="" type="text">

Mysql table type is set to : decimal(16,2)

Here's my problem:

For example:

Input format: US$ 625,695,295.00

Outout format: 625

It means, it won't save into table as currency correct format, it won't save after comma into sql table. It should be something like this: 625695295.00

How to remove it those commas and dollar sign when data is posting to mysql table?

Here's my post code:

$problem->setExample6($_POST["example6"]);
$_POST["example6"] = $problem->getExample6();

Thanks in advance.

SOLUTION: PROBLEM SOLVED!! SPECIAL THANKS TO chris85 Here we go:

   $problem->setExample6(str_replace(array(',', 'US$', ' '), '', $_POST["example6"]));
   $_POST["example6"] = $problem->getExample6();

Here's a javascript approach you could use to strip the US$, whitespaces, and commas.

var string = 'US$ 625,695,295.00';
alert(string.replace(/(US\$|\s*|,)/g, ''));

I'd do this in PHP though.

$_POST["example6"] = str_replace(array(',', 'US$', ' '), '', $_POST["example6"]);
