I am unable to understand your question. If you mean some good WYSIWYG editor then try http://www.solmetra.com/en/disp.php/en_products/en_spaw/en_spaw_about Its really awesome.
A very extended list over here. Enjoy the testing of most of them There are a few very good ones between them, and indeed, SPAW is a very good one too!
HTML wysiwyg editors are in at least 65% of the cases PHP-compatible; mostly because the HTML is converted to code before posting to by example a PHP script
Well, okay lol, but for me both are okay, I think he means a HTML editor that understands PHP lol ... and if not, there are no possibilities out there of course
Yes not an HTML one - I know many of them. I was asking for a PHP editor - dont know if they are available or not. So if someone want to edit their php site - Do they require PHP knowledge ?
Aha, okay I get it now :$ Well, yes, if someone wants to edit their php site, they definitely require PHP knowledge, except if the PHP is always the same, you could make yourself a custom script
