The W3C Validator is already known on the Internet and is used many thousand times to site to check on a daily basis HTML conformity. The online tool provides several options for this testing be carried out, including an API. Around this API can also be found quickly a few wrapper scripts to facilitate the handling of it. I've looked at a few and I could not find a simple PHP script that only hinschickt a specific URL to W3C Validator and entgegenimmt the result. Something like this as you know from the Validator plugin from Firefox. Just click and read result, pre-configure anything or initialize.
Since I have found no meaningful script for my needs, I wrote a short hand its own. This PHP script I use in connection with Jenkinis flv and validate flv during the Deploy process the websites of the respective Web project. This ensures that with each Deploy valid HTML is delivered.
Quite simply the matter was not because of the service of the W3C Validator is not necessarily stable available. Therefore, the script checks every URL often, to a reasonable return from the W3C Validator returns. But I assume when the W3C Validator 3 times consecutively nothing vernüftiges returns, he is simply not available, and the test can not be carried out in general.
