PHP and HTML Validation?

Copy linkTweet thisAlerts:

If I wanted to go to the W3C validator and make sure the markup on my site index was correct, would it matter if there were PHP scripts running on the index?

@Joseph_WitchardauthorJun 23.2008 — Is this true for all web languages? Like CSS and other scripting languages?

@NogDogJun 23.2008 — It is true for any [i]server-side[/i] processing, such as PHP, Perl/CGI, JSP, ASP, etc. CSS is not a scripting language, and will be accessible to any client that accesses your page, including the validators -- particularly including the CSS validator. ?

@Joseph_WitchardauthorJun 23.2008 — So if you had CSS embedded in your page via the <style></style> tags instead of linking to an external style sheet, it wouldn't mess the HTML validator up?

@NogDogJun 23.2008 — The <style> tag is part of the HTML specification (see [url=http://www.w3.org/TR/html4/present/styles.html#edef-STYLE]). As long as it is correctly implemented, then no, it will not generate any HTML errors, just like every other HTML tag defined in the spec.
