I don’t want to go into the trouble of uploading it on a live server to validate it on validator.w3.org It’ much easier to ask don’t you think?
You don’t have to upload your files to a server to validate them at W3.
It gives you the option to validate by “File Upload” and “Direct Input”.
Again there is the issue of uploading it . direct input won’t do… I have some files included using php includes and some contents on the database , and copying snippets of the code on the direct input text box won’t validate
