$farr = array(
"/s+/",
//Filter out excess whitespace
"/<(/?)(script|i?frame|style|html|body|title|link|meta|?|%)([^>]*?)>/isU",
//Filter
To add filtering of
"/(<[^>]*)on[a-zA-Z]+s*=([^>]*>)/isU",
//Filter the on event of javascript
);
$tarr = array(
" ",
"<\1\2\3>", //If you want to directly clear unsafe tags, you can leave this blank
"\1\2",
);
