Ok, kind of a misleading title, but I really don't know how to phrase it. My question is legit, though.

Basically, how would I preg_replace everything on the page?

Let's say I have a bunch of spans. If there is a URL parameter '?edit=true', then turn all of those spans into inputs. But only the spans with the id='editable'. Is that possible with PHP?

Thanks

Are you trying inline editing? If yes, try searching "jquery inline edit"

You may to use http://php.net/ob_start and http://php.net/ob_get_clean

Those functions help you to get parsed content, then you may to replace any page part as you wish.
