K opening this again, ive made a function to remove bad characters from my string, I've got these on the list so far, is there any I've mised;

& - gets replaced with &
OR - with O<i></i>R
' - removed
" - &quot;
> - &lt;
< - $gt;

Would that be enough to stop injecting?

htmlentities( $string, ENT_QUOTES ); will be fine. (as in, just that)
