Prevent curl connection to adtwirl server for pc users.

[GumSlone]

Since there are no pc ads in the adtwirl network and every pc user who clicks adtwirl ad will see this message.

ad id:633
You can access this ad only with a mobile phone.
Mobile advertising powered by adtwirl.com.

you can block the curl request to adtwirl network, if you modify the code a bit with the following function which you can download from: Detect Mobile Browsers - Mobile User Agent Detection

this will reduce the usage your server ressouces and your server load.

you need to add this piece of code on the top of the adtwirl_request function:

$mobile = mobile_device_detect();
if($mobile == false) return ''; 

combined it will look like:

function adtwirl_request($ads_number = 1, $use_array = true)
    {
      $mobile = mobile_device_detect();
if($mobile == false) return '';

      /* Enable free ads (true = enable ; false = disable ) you will get points instead of Money for this ads which you can use to advertise your site, if this ads are disabled your site will show only cash ads */
      $free_ads = true;
      
      $request_method = 1; /* You can chose here the request method for ads, but the best value is 1 which stands for curl request method. Any other value will be readfile which is not recomended. */
      
      // Do not edit from this line

      if ($use_array == true && $ads_number > 1)

    } 

Done

Adtwirl gives me problem On my html Pages. Basically my pages are valid html 4.1, but when I add your adds then a user of mine says pages are not valid. Then I try to validate those page. I saw your ads give me Warning. not the actual error. but it gives me warning.

The sequence <FOO /> can be interpreted in at least two different ways, depending on the DOCTYPE of the document. For HTML 4.01 Strict, the '/' terminates the tag <FOO (with an implied '>'). However, since many browsers don't interpret it this way, even in the presence of an HTML 4.01 Strict DOCTYPE, it is best to avoid it completely in pure HTML documents and reserve its use solely for those written in XHTML.

dont know what its all about, but with w3c validator and standard mobile doctype everything should be ok.
