I am running validation on one of my new PHP pages.

This is the line:

<?php require_once( "../../webassist/security_assist/helper_php.php" ); ?>

This is the error:

Saw <?. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)

That means that your PHP script is not getting parsed through the PHP parser.  Do you have the correct file suffix?  You can check some of this with a little script like this one, shown here in its entirety.

<?php phpinfo();

Open in new window

Yes. the file is:  default.php and it displays just fine.

I get those errors when I run the Validation in Dreamweaver

Your script shows a page with all PHP info

maybe you need to set expilictly that the file is of php type.

but best try to run this file in a browser within working PHP container (server) to see if the code works.

if it works, then probably this is only Dreamweaver validation issue.

The page works just fine, its only when I run DW validation that displays those errors.

Dreamweaver was a good tool for building simple web sites many years ago, but nobody does that any more.  Today we use things like the Laravel framework instead.  And you can feed your finished script directly to the validator -- you do not need (and probably do not want) the interference of Dreamweaver.

Well .. I am using DW because I have been using it for years and I currently have some great extensions (DMXZone) and (Webassist) which help me code fast. So for now I will stick to it and about the errors I will simply ignore the DW hints  :)   Plus I can't validate a page that is inside an intranet I don't think.

Don't know about your intranet, but you can probably copy the HTML and paste it into a public-facing document then fire up the validator.  I often do that just to make sure I'm on track and not doing something like accidentally duplicating ID attributes.

Don't do it that way.  DW can't parse PHP at all, so what it does is transfer the entire page markup (minus things like Template or Library code) to W3.  So all PHP code gets treated like HTML.

Always, always make W3 look at RENDERED code.  That means giving it a working web link.  Use Firebug and a browser to make this fast and easy.

Firebug and a browser
Google Chrome Dev Tools are pretty good, too.
