Hi dear friends!

How can i resolve this duplicate problem with edit the php code file?

My trouble is google find that :

and

http://vietnamfoodtour.com/.....booking.html

are different page, but they are one but google indexed both of them. And the Duplcate content is raised

how can i notice to google that they are one?

You can use 301s or canonicals even if it's driven by one template. You'll have to set up the 301 rules based ont he URLs themselves or create dynamic caonical tags in the code. if the CMS can drive multple URLs, it can drive multiple canonicals.

If you can't sort that out in the code, you can't use NOINDEX either. You'd end up no-indexing every version.

Your other best bet may be to ignore the ID= parameter in Google Webmaster Tools. Personally, I consider that the worst of the three options, but it is the easiest and it should help a bit.

Since you have said that you cannot modify the PHP code, you can use the following tag in robots.txt file to stop search engine from indexing the pages -

Disallow: /?mod=*

However, make sure that other pages are not getting blocked by it.

All of the code is decode by one file php code so i can't use canonical or redirect 301.

Maybe i should use noindex meta tag.

You can use the rel canonical tag but you are better off redirecting one to the other.

All the best!

hello, You can put a 301 redirect on one of the link to the other (which u prefer to be used), that wil fix this issue.
