    Filter out unwanted PHP / Javascript / HTML tags.

    This class can filter input of stray or malicious PHP, Javascript or HTML tags and to prevent cross-site scripting (XSS) attacks. It should be used to filter input supplied by the user, such as an HTML code entered in form fields.

    I have tried to make this class as easy as possible to use. You have control over the filter process unlike other alternatives, and can input a string or an entire array to be cleaned (such as $_POST).

    ** 1.2.0 features MUCH better XSS prevention **

    Example usage using string input:

    <?php

    // include class file
    require("class.inputfilter.php");

    // setup user-defined arrays
    $tags = array("em", "br");
    $attributes = array("title", "selected");

    // create customised filter object
    $myFilter = new InputFilter($tags, $attributes, 0, 0); // more info on constructor in readme

    $before = 'I <em TITLE="some text" foo selected>hope</em> this <stron<strong>g>works</stron</strong>g>, <br>dont you?';
    $after = $myFilter->process($before);

    ?>

    $after: I <em TITLE="some text" selected="selected">hope</em> this works, <br />dont you?
