PHP - Stripping PHP content inside of textbox?
<p>Hey guy's i'm making a website which involves submiting an ad for a gameserver. I'm wondering if it is possible to strip PHP related tags from the content of the textbox? As  if I leave it how it is now, It may become a security risk later on. Currently the only thing I am doing to the content is nl2br(). What is the best way to do this?</p>

<p>Thanks.</p>
