Make site open only in mobile [closed]

Use a class in php to detect whether it is mobile or not:

    <?php


function mobile_device_detect($iphone=true,$android=true,$opera=true,$blackberry=true,$palm=true,$windows=true,$mobileredirect=false,$desktopredirect=false){

  $user_agent       = $_SERVER['HTTP_USER_AGENT']; // get the user agent value - this should be cleaned to ensure no nefarious input gets executed

  $accept           = $_SERVER['HTTP_ACCEPT']; // get the content accept value - this should be cleaned to ensure no nefarious input gets executed

  switch(true){ // using a switch against the following statements which could return true is more efficient than the previous method of using if statements



    case (preg_match('/ipod/i',$user_agent)||preg_match('/iphone/i',$user_agent)); // we find the words iphone or ipod in the user agent

      $mobile_browser = $iphone; // mobile browser is either true or false depending on the setting of iphone when calling the function

      $mobile_browser = true; // set mobile browser to true

    break; // break out and skip the rest if we've preg_match on the user agent returned true

      $mobile_browser = true; // set mobile browser to true

    break; // break even though it's the last statement in the switch so there's nothing to break away from but it seems better to include it than exclude it

  header('Cache-Control: no-transform'); 

  header('Vary: User-Agent, Accept');



  // if redirect (either the value of the mobile or desktop redirect depending on the value of $mobile_browser) is true redirect else we return the status of $mobile_browser

  if($redirect = ($mobile_browser==true) ? $mobileredirect : $desktopredirect){

    header('Location: '.$redirect); // redirect to the right url for this device

    exit;

  }else{ 

    return $mobile_browser; // will return either true or false 

  }

} // ends function mobile_device_detect

?>

Then in the index of your site I do this:

<?php    
    include('mobile_device_detect.php');
           mobile_device_detect(true,true,true,true,true,true,'../mobile/index.php',false); ?>
    <html>
        ...pagina com aviso que so funciona em mobile
    </html>

I think it would not be "just on mobile devices" but rather responsive.

Understanding your side, I think you'd like it to be used only on mobile devices and if some desktop does not show up right?

I've never seen a mobile-only site (inaccessible via website).

I think it would be interesting to develop the application encapsulated to the application (if it has) and not indexed to the search engines.

I hope I have helped. I remain at your disposal for further clarification.
